    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.

u/rep_movsd

x.fillRect(i+t%8*w,j+(t>>3)*h,1,(j+(i-j+r&(i&j)))*r%2) is also interesting
u/rep_movsd

x.fillRect(i+t%8*w,j+(t>>3)*h,1,(j+(i-r|(i^j)))*r%2) also has some interesting tiles
u/DataMeta

cool way of doin a 2d scan!
