    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.

The drill found a #default

u/tomxor

Hah, awesome idea! This reminds me of those transporter rings from Stargate
u/tomxor

This can go a little bit smoller: ((X**2+Z**2)<.1)&(M=Y-S(t))>0&M<.8&M%.1<.05 => s<.1&(M=Y-S(t))+1&M*18
u/Agnes

You're right, I completely forgot s was already X^2 + Y^2!!! I would never have come up with the binary &M*18 though
