    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.

Hot damn! that looks fancy! and i thought i was doing something great by just adding random colour :D
u/Xen

always save your code to one side before posting, play with it to see if you can squeeze something extra out.

Helpful tips! Is there an IRC or some messaging service to hang out with fellow dwitters?

Under 100 chars. Unfortunately the moon doesn't fit inside 140. :(
