Wonderful video! I'd watched before a few times about the concertina tower itself, but now (after your advice), the raised, not-quite-flat platform is more what intrigues me and may be the solution to my current dilemma of a right-angle v-fold "sagging". Great idea! Thanks.
I'm sorry, I can't help on that. I don't really know much about mathematics. Anything that I've worked out that applies to a particular mechanism I try to include in the tutorial.
I am glad to see you back. To celebrate that I have just bought your book.
HES BACK!

Where can I find a book about mathematics that underlies all these properties of folding, etc?
