    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. Here's 126, maybe room for snowflake code with(x)for(fillRect(0,0,i=2e3,i);i--;)clearRect(50,9,!setTransform(s=2+i%7,0,0,s,i,i&&(i*i+t*s)*50%2e3-400),i&&!rotate(i+t/4))

u/magna

I was expecting this to happen one day...
u/magna

Wait. How the hell are you rendering the "ground"? I don't get it. Explanation please.
u/nystrand

It's the "(O" chars at the beginning of the code decreasingly scaled down from the large initial scale. I had to find a variable name that "looked good", - went with O which made coding confusing as it looks like a zero :)
u/magna

This is nuts!
