Picture of a 3D computer model of a Reuleaux Tetrahedron.
What is this?
If you were thinking Reuleaux Tetrahedron you're correct. IRL they're shaped like a pyramid but roll like a ball.
1 state change and 3 moves later, I can't find the Reuleaux tetrahedrons I 3D printed so I'm printing up some new ones. #lulzbot #3dfuel #stem #illusion #science
