Man. This channel, every other year, takes me back to my 16 year old self subscribing to it back in like 2007. One of the first channels I ever subscribed to. Always warms my heart to see another video posted on it. Thank you. Wish you all a Merry Christmas and happy new year
hey man! only trick used was throwing cat food on the surface to get the kitty up there haha. it all has to do with the “shadow” being cast by the cylinder. the shadow is fake. it’s printed on the checkerboard. so you mind thinks it’s real and automatically adjusts the shade of the square
@@brusspup But how did you mange to prevent the real shadow of the cylinder from interfering with the fake shadow? My mind is seriously broken trying to think about the lighting setup...
Dude, thanks for being (one of) the only comment(s) here addressing how incredible it is to reproduce this illusion in real life. Everybody else either has no idea how amazing this setup is, or they're too distracted by the channel's annual upload to notice lol
@@MrRoboticBrain I think the light in the back left is very diffuse, so doesnt cast much shadow. Another light in the front right casts the main light over the scene (you can see the shadow on the other non-grid side of the cylinder). The shadow is just a printed illusion.
It's amazing how many people like me who have subbed for many years are reminded of all of your videos as soon as you release a new one. Feels like a throw back!
I legit just remembered this channel & wanted to watch some of your old videos, but then I realized you just uploaded 15 minutes ago after 2 years of silence. Absolutely incredible 👏👏
Seeing a rare Brusspup video uploaded always puts a genuine smile on my face. The editing on this was pretty wild aswell. Merry Christmas and a Happy new year!
Wait, what? At first, I thought it was the usual shading illusion, but then when the "black" tile was moved onto a "white" tile, I realized it was a different illusion altogether: how come the tile does not become darker when going into the shade? The illusion is not caused by the actual lighting (if I understand correctly)! It broke my mind for a while, well played! I hope viewers will take the time to appreciate it.
The illusion is cased by the fake lighting: Both the big light you can see black cylinder and the shadow the black cylinder cast on the checkerboard are a lie. Look at the shadows of everything else: The scene is actually lighted from the front. If the scene was actually lit as is it pretends to be, your brain would be right: The square would have to darken it's true ("unlit") color in order to keep the same apparent brightness when it move to a more lit area of the scene.
The light on the back-left is just for show, there's a big light on the front-right, which is shown in the first shot of the video. You can also see the effect of that in the shadow of the cat. The tiles are just colored in such a way to mimic the on-paper illusion, and are not "colored" due to a shadow being casted on them.
Damn it's been over 10 years now when I started following your content, back then with the old original CZcams account. And in the meantime I forgot and today I randomly remembered your channel and am happy to be back, a throwback to the good and seemingly easier days. :)
No matter what I watch, where I go on the internet, I always end up gravitating back here. I’m always excited to see what new things you’ve got in store for us, I can’t wait for the next video!
Thanks for the effort and the contribution.... It's the refraction that makes it appear that way..... it's like many surfaces that get a "different" color when the light falls on them differently.... Apparent but not matarial
Amazing work. 👍👍👍You wrote down that some shadow was paint. I wonder why and what does it change in the illusion. Was it necessary to fool the brain? I also wonder if the effect was the same if you're physically there?
I’ve been following you since Grant Thompson (may he rest in peace) did a collab with you and other creators. Its been like 8 years now i believe. You have never disappointed
This channel is like that old happy memory you remember when everything is bad but you need a smile. Merry Christmas brusspup and happy new year!
such a nice comment. thank you!
A true legend of the game. See you all again in 2 years
That's all this man is. Game. No substance at all.
Hey look who it is!
It’s look who it is!
@@funnyglitch a great entertainer you are
I‘m always so happy when you upload once a year. Videos are great, editing on point! Keep up. ❤
thanks!
@@brusspup more fake poop tutorial please
Me too
man comes out once a decade, blows everyone´s mind and retreats again
hahaha
But it’s a woman
@@bogjesrbin484 It's his gf/wife
Always a joy to see new Brusspup!!
Damn, I can't tell you how good it felt to see your name in my notifications! Thanks for all the content over the years!
wow thank you!
Me too😍
One of the first CZcams channels that I subscribed too way back
That's crazy... I can't believe that cat isn't real... optical illusions are very powerful!
the cat is actually real.. ive got a full litter box to prove it
@@brusspup that smell is just an illusion
Schrodinger's cat
Brusspup, idk if you’ll see this but I’ve been watching your videos since I was 10, it’s amazing to see how far the channel has grown.
It's great to see this channel back... I always come back for all the beautiful piano pieces
Very old memories unlocked. Glad to see you still uploading.
I agree with you

I was just watching you for the first time in forever today and then you upload for the first time in 2 years!! So perfectly timed
thats crazy! thanks for watching
I love how you guys just pop out every 10 years to bless us with a cool video
I'm glad there are still channels like this. Quality over quantity.
Indeed! 👍
Yeah but one video per year is kinda exaggerated if you ask me 😂
When the world needed you the most, you returned
Alright, you got me. Assuming there's no camera trickery going on I have no idea how you did this in real life. Tutorial pls? Excellent video

Even better illusion would be if your cat was light/dark grey, and it moved between the squares 😮
hahaha. good one!
Been following for years and look forward to see your releases! Keep it up! 😄
Crazy how the shadow is entirely fake, nice work :)
thanks!
I'm pretty impressed at how that 'light' works
It really sells it
It's amazing how many people like me who have subbed for many years are reminded of all of your videos as soon as you release a new one. Feels like a throw back!
A true OG returns! Hope you've got more coming soon!
Omg you are alive! Stay with us please!
Please post again! I could watch every single one of your videos!
I legit just remembered this channel & wanted to watch some of your old videos, but then I realized you just uploaded 15 minutes ago after 2 years of silence. Absolutely incredible 👏👏
thats amazing! thanks for watching
Been watching your vids for so long. Started with the KipKay battery hack parody. Glad to see you still uploading, even if infrequent! Happy Holidays!
Seeing a rare Brusspup video uploaded always puts a genuine smile on my face. The editing on this was pretty wild aswell. Merry Christmas and a Happy new year!
The legend is back!!!
New stuff soon hopefully!!
Super high quality for such a hiatus.. Glad to see you haven't lost your touch!
Wow ..!!! You guys are still alive ..!!! Thank god ..!!! Was getting worried ☺️
still here! :D

I suppose it's something to do with the glossy paper and how it appears lighter or darker depending on the illumination angle
I hope we get the answer cause my mind is totally blown

@@progreon That was my conclusion too, there is no real shadow, only fake shadow by coloring the tiles.
The return of the legend. And by legend, I of course mean Mini-Me the cat.
hahaha
Long time no see! Thanks for the vid and merry Xmas!
Seeing this classic recreated in real life is totally astounding. Thanks for blowing my mind anew!
Really interesting illusion.
Thanks for sharing with us🎄🙂🤝🤝🤝
It's always a treat to see another upload. A classic illusion demonstrated in real time and also featuring a cat. Have a Merry Christmas.
Ahhh I remember this 😭 so cool tho, welcome back! :D
P.S see you in a year
hahaha thanks!
Do more videos pls ❤

Hello Great Ilusion :)
No matter what I watch, where I go on the internet, I always end up gravitating back here. I’m always excited to see what new things you’ve got in store for us, I can’t wait for the next video!
I love your channel! I've been watching you since i was 10
my brain still can't comprehend it
I clicked the notification as soon as I saw it! Welcome back, we've been waiting for you! 💗
thanks for watching!
@@brusspup thanks for your amazing content 💫
Been a minute! Good to see another video!
Oh yeah!!, Glad to see that you're still alive! Great illusion too!
OMG look who's back! This is a cool xmas gift, thanks!
Always loved the drawing of this optical illusion, great to see it in 3D
A wild Brusspup appeared! (shiny)
Been a while! Great to see you back!
thanks!
I've seen versions of this.
This is THE BEST!
I like how you actually made the famous shade illusion real.
I love that every element of this video is original. Brilliant stuff.
I didn’t expect this on my subscriptions list!
This is a very good early Christmas present,
Damn, you're finally back. And it's a goodie. :)
I genuinely thought this said "10 years ago", not days
Leuk om je weer terug te zien hier!
Thanks for the effort and the contribution....
It's the refraction that makes it appear that way..... it's like many surfaces that get a "different" color when the light falls on them differently.... Apparent but not matarial
It's been 2 years.... I missed these
You're alive 🥳
Hey, long time no see! Glad to see you're still around.
Hard to believe it was 2 years ago when your last video was posted, and even then I get excited even more each time you upload
Cool music and sound FX
I swear this dude comes out of nowhere to drop a video then dips for like 2 years just to do it all over again
Like Jon tron but longer
This was one of the first channels I subscribed to almost 10 years ago
Hey there..... been a while, love the content ☺️
It makes me so happy to see a new brusspup video. Really cool to see this illusion irl.
I'm always surprised when you upload a new video. It's a pleasant surprise
Woaaah it's them! It's always a delight to see these videos and before the holidays too!
Good to see you're still at it occasionally love the video
This channel helped me in my 4th grade project
My favourite optical illusion in my favourite channel of optical illusions! :D
What a great wish of Merry Christmas! Thank you!
Hey! Been a fan since 2009
thank you!
Dude no way did brusspup come back to make my favorite illusion of all time IRL.. must be a Christmas miracle. [=
always love the original music - Happy Holidays!!
Damn is it 2015 again???? Love when theres a new Brusspup video!
What the hell, this lady is alive? Nice!
Heeeeeey! Long time, no see!! Welcome back!
Imagine how much more successful this channel could get if you made shorts
im planning on it
This channel is pure nostalgia to me
I have seen computer generated diagrams of this before, but I’ve never seen anyone recreate it in person. Very cool, thank you
Amazing work. 👍👍👍You wrote down that some shadow was paint. I wonder why and what does it change in the illusion. Was it necessary to fool the brain? I also wonder if the effect was the same if you're physically there?
I thought I always understood this illusion until I saw this video
This illusion always amazes me.😃😃
same.. it’s crazy trying it in person because you see it right in front of you and it still works
Always there when we need you 🙌🏻
Amazing. I think I saw this before somwhere 🤔
Delightful, as always.
No way a new vid! Thank you!
From the thumbnail I thought "This illusion again?" but the actual execution of it was awesome!
I’ve been following you since Grant Thompson (may he rest in peace) did a collab with you and other creators. Its been like 8 years now i believe.
You have never disappointed
Nice cat! 🥰
SO freaking awesome!
I experience this while painting. It makes it difficult.
Brusspup? Now that’s a name I haven’t heard in a long time…
Actually Albert Einstein never said that quote, look it up.
And that is why I hit the bell, could have easily missed this one.
Perfect video.
Wow..... Welcome back.... Where have you been.... Thank you.
hope all is well brusspup. i used to LOVE watching your videos. i mightve been 12 years old. 23 now.
