First, draw Then, press space Finally, watch it spin with the variable
I made this because in my geometry class, I'm learning how to rotate thing using math, but it's really boring. The formulas are "If you rotate 90 degrees, then (x,y) -> (-y,x)." But these formulas aren't useful for anything other than 90 degree rotations, and I wanted to actually make it using math and not useless formulas.
