    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.

Great!

u/magna Thanks, but I made it on a slow PC, now that I'm watching this at home it's way too fast. Is there a way to handle this in code?

@noel: i'm not really sure. But i think the best way to get it work same speed on all PCs it to use t (timer). Btw, the function u(t){your code} will be called 60 times per second. So using d-=4 should run same speed on all fast PCs - but slow down on older slower PCs.

Btw, it looks really cool with this green shining spikes.

I like it, running fast or slow! Viewers can always add t/=2;
