    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.

Pascal's Triangle. Could easily be shorter (probably)

u/Irratix

Still had a lot of room left, so I made an easily visible rowAmt variable for you to tweak :D

Stopped working now. I think the site has changed the way it executes dweets.

At present it should be .slice(109,-1)
