    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.

Make this dweet fullscreen, wait for counter to go from 10 to 0, then focus your eyes on the number counting from 60. When the counter goes down to 0, look off from your screen and you will be disoriented
