    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.

I hadn't played with an #attractor lately. They really play to my strength of "change random stuff until something neat happens".

How do I mark things as a remix?

You have to make your dweet by editing the one you want to remix and a submit button shows up.

I see now, thanks.
