    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.

Nice! although i think technically crystaline makes it quartz; glass is amorphous but I no idea how that would look.

Nice color! You can save 2 characters using: c.width&=k=4e3
u/rodrigo.siqueira

And you can save 2 more characters by placing "c.style.filter='invert('" at the end, instead of the trailing ";"
