    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.

Sliced Dots #beesandbombs

Golfed 3 loops into one. Lowest bit of i determines half-circle, next 5 bits determine X and the rest determine Y

i&62 = (i>>1)%32*2 = X*2

There's a lot of really clever tricks in your dweets. Keep them coming! :)
