    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.

MORE disks >:) #beesandbombs

u/anotherkitten

stop being so good
u/katkip

i love your beesandbombs dweets
u/pavel

I call fill just once, the black bits are a single connected shape that zig-zags, the messy edges are hidden offscreen.
u/pavel

I use 1/(1+9e9**x) to smooth step but even rows step twice in one cycle which is done by adding (j|t)%2 as offset.
u/pavel

In hindsight ~~x+(x%1)**9 is better for multi-smooth-step animations.
