    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.

Now that's beautiful!

I love it, but I really wanted to do it without compression. I even tried using fillText('●'). See my remix for the closest I could get.

[Dwitter Compressor V 1.2] Click around until you find a pesky INPUT element, then paste your code in and click away to get your code compressed. From there, just copy the text In the INPUT element, and paste in your dweet to post it. It still struggles with ascii values below 16, and must have an even length input (NO UNICODE). The limit of characters for a dweet is 184 using this compressor.
