    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.

Spinning 3D model. This one is pretty CPU-heavy, gotta compromise for size

Very nice!
u/p01

It looks super clean!
u/sigveseb

is it spinning clockwise or counter-clockwise? :)
u/FireFly

shhh… it's rotating CCW I think, but cheating with the Z-axis/depth ordering means the faces are kind of haphazardly drawn :P
u/Xen

its transdimensional, you meant to do it! ;-)
