    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 tunnel looks so clean!
u/iverjo

Thanks :) My aim was to create a vertical camera tilt effect. I ended up just moving everything up and down. Kinda resembles tilt ^^

This doesn't fit, but it compresses the lines so they don't overlap: x.lineWidth=s*s*(1+S(t)*S(i+.45)/2)
