    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.

u/tomxor

Very neat. The migration of the points gives it quite an etherial look.

These are non-repeating mountain ranges, using a similar formula used in my #JS13k game Space Huggers

The first game where I saw this effect was in Moon Patrol, I liked it a lot, it was great and also had a great music. I think it would not be difficult to recreate Moon Patrol from this Dweet.
u/andrea270872

moon patrol ate so many of my coins!! :D
u/tomxor

Pretty sure I first saw the effect in StarRay (Atari ST), I think I enjoyed the music more than the gameplay, no coins though :P

Very cool and smooth paralax landscape
