    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.

Nano Snakeskin

u/bandaloo

this is great! i'll definitely be using this substitute for a doubly-nested for loop
u/DataMeta

agreed, cool trick! even more succinct than the nested hack I've been using, and the perf increase from bitwise ops is welcome
u/tomxor

Yes, I've used this so much, I guess it's just more obvious in this one. I've taken technique a step further in d/20707 converting yonatan's 3 loops into one. bitwise can be very powerful to manipulate the variables a loop traverses.

I once made one similar, a "Polygon showcase" from 1 to 8 vertices: https://www.dwitter.net/d/10692

@ u/rodrigo.siqueira very nice and concise! i think maybe there's room there for one more loop to iterate through the "web" like
