    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.

[dwitter character compressor V 1.0] Step 1: drag and drop a program (with an even character count) in to compress, Step 2: look in your browser's developer tool for an error with seemingly random text, Step 3: copy that and paste it in place of my compressed program. {Please note that the largest program you can have is a length of 184}

also it does not function well with new lines and it can only compress ascii
