    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.

Slideshow v2.1: A minor bug fix. Previous versions no longer work because of dwitter improvements. Good news is we can now use }{ in dweets for one time code.

u/AnnanFay

See https://github.com/lionleaf/dwitter/issues/2… for details on the improvement.

High resolution Game of Life with a constant ground layer. It will eventually start cycling. To increase FPS swap 2e4->6e3. To hide the ground swap 4e3->5e3.

Was wondering how the shape evolves as the constant in C(99*i++) changes.

u/AnnanFay

Change 2e3 to 99 for a more vigorous experience.
u/magna

Awesome!

Oh, why do you use kanji characters as variables?
u/AnnanFay

The kanji are so I don't accidentally redefine a variable which something uses. For example there's code which does t||(_=c.width) so if I use _ it would break the code. It will break stuff which uses these kanji, but right now this is the only dweet using them.
u/fujimotos

Nice. I didn't know that they are valid variable names...
