    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.

u/nick

Wait? How did you get 145 characters?
u/pangolin

It says 140/140 for me. If you copy it into notepad++ or something I think it counts linebreaks as 2, Dwitter counts linebreaks as 1.
u/recursive

If you edit it, suddenly the character count becomes correct also.

Nice

Nice work! Maybe there's hope for imageData after all. ☺️

This is great, and what a luxurious use of 100's instead of 99's :P

Direct pixel manipulation. Interesting approach but it looks like it might always be larger. Does this have a dweeting application?
u/hypothete

I'm not sure. I put this one together in case people had ideas on how to shrink it.
u/veubeke

@hypothete new ImageData(W,H) saves some bytes as does incrementing i by 1 instead of 4 and calculating image data size manually. https://www.dwitter.net/d/2069
