    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.

nice!
u/yonatan

Thanks. A little too fast, should have been t/8 instead of t/4...
u/aemkei

Thought the same. t/8 is really a calm beauty!

Yeah, my screen does 30Hz so I only notice it when exporting to a gif.

Clicked random and remixed the first dweet

I clicked random and this was the first dweet, thought it would be funny to remix although I'm not very good at it
