    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.

Same thing, using fetch: F=async I=>T[I]=(await(await fetch('/id/'+I)).text()).match(/u\(t.*([^]*?) }/)[1];eval(t?T[1494]+';'+T[888].slice(23):F(1494),F(888))

Does anybody know how to make this actually bounce off the sides in 140 characters?
u/BirdsTweetCodersDweet

Better resolution if you want : for(c.width|=i=999;i--;x.fillRect(M.min(1870,M.max(0,960+400*S(a=t+i/4)+800*S(t))),M.min(1030,M.max(0,540+400*C(a)+400*C(t/3))),9,9))M=Math

Great!
u/davidsharp

@Xen, you should totally fork it, that looks great
u/New_Core

on Xen's version can remove t+i to i ... no need to spin it if it looks like a line.
