    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.

Counter example

u/kyleminto97

I saved a whopping three characters haha - throw t?T++:T=0;
u/jylikangas

throw frame
u/KilledByAPixel

throw t|0 Save 2 more chars, it just counts a bit slower ;)
