Logic Gates with Cubelets by signal propagation

We implement majority and AND gates (with negation NMAJ and NAND) with Cubelets robots. Binary values are represented with the propagation of light (on=1, off=0), they compete for the space and interact in a boolean operation. This way, one lightness cube handles the majority operation operating on a T-function. If a MAJ operation is true hence the light is catch by a brightness cube and display the final result. Also, if you fix the third input as 0 then you can simulate an AND gate but if you fix this value as 1 then you can simulate an OR gate. Finally, to get NAND, NOR and NMAJ gates simply we connect an inverse cube.
The source code to implement a MAJ gate with Cubelets is available from: gist.github.com/RQF7/87b89a3c...
