    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.

i tried to make an illusion but it didn't work

u/pavel

Here is how far I got with(x)for(k=8;k--;beginPath(fill(arc(960+6*o,540,k?k-7?300:2e3:200,a=30*t-o,++m*22/7+a,k%2))))m=k<1|k>6,o=m?0:[0,1,-1][k-1>>1],fillStyle=R(a=m?170:k%2<<8,a,a)
u/pavel
