    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
u/tomxor

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

How many digits of pi can you store in a dweet? Here's 367 (including leading 3

u/katkip

▓ nice ▓ unicode ▓ characters ▓ there
u/Irratix

Haha, you kinda run out of ASCII when you store a number in base 55394 :P

Frankly I'm not even sure precisely what's happening but it sure looks fun, although a bit shakey.

u/Irratix

Effect may differ depending on your browser, it's largely related to built-in compression. I made it on Chrome.

How long could it possibly take to just draw a triangle? Answer: About 18 minutes.
