    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, dots on the beach. I used 5,5 so I could see the dots more clearly, and t*=15 for speed

New 4-1 compressor proof of concept! In this example the compressed code is 208 chars.

u/KilledByAPixel

#COMPRESSOR replace $ with your code... $="for(c.width|=i=9;i--;)x.fillRect(400+i*99+S(t)*300,400,50,200)";n=[...new Set([...(';'+$)])].join(o='');for(v=i=0;(q=$[i])||i%4;++i)v+=q?n.indexOf(q)<<i%2*5:0,i%2?(o+=String.fromCharCode(((i%4==3?55:54)<<10)+v),v=0):0;throw 'for(I=O="";Q="'+o+'".charCodeAt(I/2);O+="'+n+'"[Q>>I++%2*5&31]);eval(O)'
u/tomxor

This is way better than my crazy delta compressor, but it's still surprisingly difficult to stick to a 32 char set.
