#3These all assume certain variables are pre-defined but nowhere does it say what they are.
Edit: If you hit "New dweet" it tells you.
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.

It's running in the browser. Right click inspect to see it.

I've always wished they'd have totally embraced their shortcuts and added as many as possible.
they could shorten every setter and function so c.width could just be w() or c.w= and c.fillStyle could just be fs(style) or c.fs=
They arbitrary shorten somethings but not others seems well... arbitrary

174 it feels close. I dropped the text and went with numbers. (sorry for any duplicate notification spam)
with(x)for(fillStyle="#000",font="2em m",fillRect(i=0,o=32,n=1920,n);n>i;i+=o)for(j=0,a=((2e7*i^1e9)+n*t)%n;n>j&&ja-j),n/2+j-a,b),fillText(j%9,i,j)
