    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.

u/katkip

nope
u/metamero

on new code dwitter only reset canvas, document's body stills. you have to open new tab when messing with dweet's document. also the &1 is to get last bit of an number (so it indexes the string with 0 or 1)
u/Phenomenal

okay, great to know and thanks for the explanation about the &1

What should be a straight line has fractal dimension 1.9 on my lappy ;)
