Apologies for the embarrassingly newbie question.
This is more of a math question I guess than a clara.io one.
What I want to do should be simple: To have a tetrahedron with the base flat on the "floor" and then have it rotate along the Y axis, basically to make the base spin while always being flat on the floor.
For the life of me, I cannot make it work :-/
I've been googling but nothing so far.
Any ideas or pointers on how to figure it out? (I seriously wasn't expecting it to stump me this hard)
