    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..

I would be lying if I said this is what I had in mind

u/Flexi23

But no-one could look into your mind and compare. wait. no.

A glowy curve, inspired by the inverted colors of https://www.dwitter.net/d/3015 by Cantelope

u/kchplr

Noticed it is very slow in firefox, has lot of artefact on Safari and doesn't even render properly in stable Chrome. The only browser rendering it correctly is Chrome Canary. Oh, well.
u/kchplr

Here is a version which renders correctly on stable Chrome : for(x.fillStyle='rgba(0,0,0,.1)',x.fillRect(0,i=0,2e3,2e3);i<7;Y=S(i*2+t),X=(C(2*i)+C(t+i+Y)),x.clearRect(960+X*450,536+Y*500,20,9))i+=.002
