Zen garden. Circle patterns around the rock may represent waves or ripples in water.

Japanese rock garden: "Developing variations in patterns is a creative and inspiring challenge. Achieving perfection of lines is not easy. Zen priests practice this to help their concentration."

beautiful!

Parallax Mountains ⛰️

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
u/vain

Very cool and smooth paralax landscape
