    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.

Pretty
u/cantelope

ppl seem to either love or hate my more visually stimulating dweets. I agree that it's pretty, but someone else complained that it is an epilepsy-causing abomination that should be stopped. :s

Ripples! With proper quads instead. Add +Z*X-Z*16 after X*60 for perspective projection too (brings it up to 146)

u/FireFly

Another byte can be saved with with(x), but this causes a fair bit of slowdown for me. Thanks for some golfing tips from qfox and others on the jsgolf slack :)

Corkscrew-like thingy!

I realised with this one that the beginPath is actually redundant since we're resetting the canvas state each frame anyway… whoops
