    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.

[Team dweet with u/PeCaN] L-system visualizer! Change initial state (s), #iterations (i), transition rules (['0-1+0+1-0',11]), which digits correspond to 'draw and move forward' (c<2), angle (120) to your own L-system ruleset. Digits 0-9 correspond to variables/constants (for each constant, add a rule that maps it to itself, i.e. to 'i').

Ha awesome! I was surprised when I saw this, I'd seen it on the internet before and was idly scribbling on the back of my book in a boring class today. Dope stuff :D

Snowflakes with gravity acceleration and parallax

err, depth that is, small ones fall slower as if they're further away :P

#snow I think it's fair to call that parallax, just vertical

How did you come up with this?

@badthai: First I made a classic tunnel effect (like this: https://www.dwitter.net/d/205). Then I made several remixes of it by tweaking parameters. This was one of the results. See also https://www.dwitter.net/d/106
