    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.

cool!
u/sfz

wtf is going on here?!
u/FireFly

The string embeds a tiny bitmap which is simply repeated :)
u/5Mixer

This is an awesome idea! I wonder what else you could do with using strings to encode more complex(?) data. Interesting.
u/PiggyClone205

When I read complex, I immediately thought of maybe importing other javascript and cheating a bit.

lol didnt need that beginpath there, was leftover from the other one

a=255;for(i=6;i--;)x.fillStyle=R(33*t%a,66*t%a,99*t%a),x.fillRect(960+a*S(t+i),540-a*C(t+i),9,9);x.drawImage(c,-5,-3,1930,1086)
