    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.

Nice! I tried sonting similar, some time ago, but could not golf it and still make it look good -> this is how far i got (uncompressed): with(x)t||(a=[1,1],translate(960,540)),a.push(o=a.at(-2)+a.at(-1)),strokeRect(0,0,o,o),arc(0,o,o,4.7,0),translate(o,o),stroke(),rotate(1.57)

F*cking cool rubber/morphing cube. Never saw this kind of fx before. Fantastic!
u/cantelope

u/NiekD

where do you get the inspiration for cool effects from
u/cantelope

dweets are sometimes harder to be ultra specific with a goal, due to the obvious constraints, but a big piece of my whole graphics repertoire is 3D math, sooo myself? haha not sure
u/tomxor

So true. More often it's just the gradual emergence of "what if"... then after a while it may or may not fit, or by the time you've played with it long enough something else tangentially related emerges. It's all part of the fun.
