    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..

Exactly the same as the original but with 11 less characters. Thanks to u/sigveseb/ for one of the tricks.

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.

Spent some time trying to compress it, but forgot to remove the Y=y. Should be 129 bytes instead of 133.

u/sigveseb

if you do z=99.. instead of z=100.. you can get an extra byte!
u/kchplr

aah, indeed thanks!
u/kchplr

Just figured out the last statement in the for loop can also be placed in the loop body to save two more bytes. I'm new to this codegolfing thing...
u/kchplr

Actually, the first statement, not the last..
