    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.

oh you sly dog very well done

u/jylikangas

Very cool! You can save 3 bytes by removing the unnecessary %1 from t when calculating a and also doing <<7 instead of *128. If someone is wondering how this works using a+1 instead of a at the end may help. :)

Removing %1 at the end breaks the animation on my iPhone.

@pavel, if you ever find that you just can't get it working within 140b, you have 2 options, the handy compressor @ d/9207, or there's also https://codegolf.tk which allows up to 1kb with bonus cred for getting under 512 or 140.. full disclosure, i run codegolf.tk. brilliant work btw. :)

u/prplz

third option: keep trying all day
u/cantelope

@prplz, of course. how stupid of me. obviously i was advocating giving up easily.
