    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.

Extremely small tarot reader! You actually can use this #witchcraft #tool as a divination method. Here's how to use: ask a question by writing it after the // at the end (include the ? symbol). Then take a look at the result in the error section. Remember: p = page, k = knight, Q = QUEEN, K = KING, Y = cups, | = wands, ⚔ = swords, ⍟ = pentacles. Examples Q of ⍟ = Queen of pentacles, 5 of ⚔ = Five of swords, K of Y = King of cups. Have fun
