    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.

This might be a good starting point for creating dweets with rectangles that leave trails. For i = 0 a large, white, semi-transparent rectangle is applied to the entire canvas. For i = 1,2,3,4,5,6 small, black, opaque rectangles are drawn.
