    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.

Spikey circle

u/BirdsTweetCodersDweet

if you add t=0 at the very start, and kkep typing +.1, you can step through and see all the cool patterns it makes along the way :D
u/BirdsTweetCodersDweet

Kinda reminds me of the old days of logo programming as well :P
u/trancor

That little turtle was great! Good looks! I added t=~(t*4)*.1; 4 is the slide show rate, .1 the steps.

Nice!

It's binary time! Literally... Enjoy this simple binary representation of t, in just 87 characters :O! Big thanks to u/bepisTM u/chobbit u/cuteness for the 117=>88 character slicing :D You guys are awesome...

u/veubeke

A bit shorter: c.width^=0;for(i=32;i--;)t>>i&1&&x.fillRect(i*50,540,50,50)
u/BirdsTweetCodersDweet

Yeah, but that goes backwards :P... But still - 59 CHARS :O...

How about this? ~9 chars shorter, and it has rainbows, too!
