    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.

First Dweet! Its nice when bugs == pretty things.

u/wpower3

I was trying to learn the environment by implementing some 2d-as-1d indexing, and messed up my reasoning. The result still looked cool, though!

Welcome to the dwitter family!

Thanks! :)

Making errors is one way to learn and discover new things! ;)

Dynamically swapping the draw order to get proper overlapping. Change i>960 to 1 or 0 to see how this works.
