    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.

Good job! Use this for better motion —> x.strokeRect(960-i*2-A*C(a+t)+S(b/i+t*30)*i/2,540-i-A*S(a+t),i*4,i*2)

@Joachim wow, it's crazy 😂

u/baon lol maybe that was a bit too fast xD
u/lewdev

u/Joachim, Not better motion, but more a more intense experience. 🤣
