    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.

Nice! Double donuts everywhere!

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.

for(i=1e4;i--;f(0,c=2,280,i+t,💡&&⭕⭕➜🍩🍩)) f=(w,h,q,d)=>q>99?f(h+q*C(d),w+q*S(d),q/c,T(d*d+t*d)/c): x.fillRect(w+480+950*(i%c),h+510,.4,t<c)

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.

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.

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