    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.

Sculpture based on torus equation #torus - Animated version. Please come back in year 2029 to see 60 FPS version. I'm getting only 2 FPS now and according to Moore's Law (performance double every 2 years), in about 10 we'll hit 60 FPS.
