I wish I knew more super math teachers on youtube ): do you know any similar to yourself?

@gC222SA I did a video recently called YouTube recommendations

Tried 3 modules, just to see how it worked... somehow an hour later I had a dodecahedron sitting in front of me. This project has an almost skinner-box experience, as you see the result coming together.

Thanks for the video; I now have a new desk piece!

I shall attempt this. But I cannot help myself, and ask... isn't the plural 'dodecahedra'?

You said that the 5-color dodecahedron gave you a bit of a head-ache. You probably figured it out already, but one pretty good pattern is to match the side opposite the corner you're connecting your piece to. This will then cause the 6 pieces of each color to be opposite of each other, through the solid, and one on "top" and "bottom"!
