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.
second one was a bit glitchy so i deleted it, here was the code for it with(x)for(t?clip():c.width=480,save(restore(drawImage(c,-6,0))),drawImage(c,w=40,0),i=t?7:2e4;i--;t?arc(215,133,113,a=(i*4/7+.5)*Math.PI,a):fillRect(i%w,i/w|0,1,1))fillStyle=R(v=i**7%258,v,v*2)
