    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.

Re-make of d/8422 with the "u" variable re-named "d" (having a variable named "u" breaks your dweet in most views)... interestingly, this violates the new cross-domain content policy!

u/BirdsTweetCodersDweet

Could it be the toDataURL() ?
u/Agnes

I think we realised it's not actually the cross-domain policy breaking it but something else. The console errors are when you try to load corrupted PNG data, which this produces pretty often.

I think 339525*t instead of 2.3998*frames is much better. :)
