    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/13thptr

it's not a tagfail
u/katkip

it is actually a fail because this dweet isn't a compressor

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
u/tomxor

I used this same little function recently for the intensities in simulated NMR multiplets. Pretty sure this is the shortest math.
