    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.
u/karan

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