    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

A bit slow but 130 char: w=t%.8<.02?7:w/.9;m=150,y=w/m;for(c.width=999,i=m*m;p=--i*i;q&&x.fillRect(i%m*y,i/m*y,y,y))q=S(p)>0,q&&x.fillRect(i%m*w,i/m*w,w,w)

3d rotation

u/taupelink

Cool!! It's also one of those figures that could be rotating either clockwise or counterclockwise.
u/cantelope

Wow, that's amazing! Wonder if we could get some perspective in here 🤔
