    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.

Thank you! I used the array instantiation from a dweet I've seen before, but couldn't find again. Your dweets are awesome, btw!

I'd wanted to do this without any trig, using rotate() and save()/restore(), but it was about 4 bytes too long.
