    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.

really awesome. I was wishing for a colored "sea". R(0,0,Y*60) yields blue waves :)

best dwitter torus?
u/sigveseb

nice!
u/keithclark

Why not use x.fillRect((k-a*i-b*a*j)*z+899,(i+b*j+a*k)*z+500,6,6)? it renders faster and is smaller
u/mxfh

Print and connect the dots. Or do it on screen for lasting impact.
