    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.

What a clever way to do the background. I also like how you used Math.tan to get the trees.
