    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.

feature request: posting anonymously...

u/lionleaf

Why not just create a pseudonym to post with? Or do you mean to make it quicker for new people to post something? I'm afraid it would just get filled with spambots
u/SpecialAgent

nice car chase. registration keeps the quality of dwits decent, imho.
u/kchplr

I was thinking about posting anonymously once you're registred, but it was mostly a joke given I'm not so glad with the outcome of this one. :D..

How did you come up with this?
u/iverjo

@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

First line as "a=b=>128*(S(t*b)+1)" brings this to 140.
u/andy

Thanks, that's right. Didn't even realize i was over 140 :)
u/lionleaf

Are you seeing over 140 characters? On chrome it says 140/140 at least.
u/andy

weird, yesterday it said 143.
u/michelinux

It's probably because on Windows the new line takes 2 characters ('\n\r'). Use ';' instead of new line and you should have a more consistent behaviour.
u/andy

still weird, i don't have any windows machines.
u/SpecialAgent

the simplicity of that zoom blows my mind, great work!
