    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.

Yes I do anyway. What’s not to like about it? See https://www.dwitter.net/d/855 anyway. Find it most descriptive in the context of the limitations of dwitter. Btw this just done fudging and pasting around in iOS Safari when I can’t fall asleep. Just did feel like posting this one.

https://www.dwitter.net/d/23557 so with some space for setting up other buffer view, it speeds things up when treating rgba Uint8Clamped Array as single 32bit value

wondering if we could store that buffer somwhere to do truly iterative fractal stuff
u/taupelink

trippy!
