    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.

no fuckin clue how i got this in 81 characters
u/Qwitter

if you send a single pixel across the screen at this resolution (70) like fillRect(X+t,,1,1,1) you can see how the canvas has a smoothing effect by slowly pouring the alpha = 255 value between the pixels

Nice! Double donuts everywhere!
u/pavel

Not a fan of the obfuscated code. Looks nice to people who don't care to understand it but hurts your fellow coders that want to play around with it, which is a big part of Dwitter for me.

u/rodrigo.siqueira

I posted a cleaner version (remix). I usually avoid obfuscated code, but in this case it was for aesthetic reasons and for fun ("donuts everywhere" style). The 💡&&⭕⭕➜🍩🍩 part was just to illustrate, it has no functionality in the code.
u/tomxor

I think Pavel might be refering to unicode tofu, I get this too... the "⭕⭕➜🍩🍩" bit renders but almost all the other non-ASCII chars are tofu. I think it depends on what browser/OS combo you have.
u/tomxor

... and which fonts you've bothered installing.
