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."

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

u/rodrigo.siqueira

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

Genius.
u/Joachim

Wow. This is very clever
u/rodrigo.siqueira

Now I can't look at city buildings without thinking about this. See https://en.wikipedia.org/wiki/Tetris_effect The Tetris effect (also known as Tetris syndrome) occurs when people devote so much time and attention to an activity that it begins to pattern their thoughts, mental images, and dreams. E.g. People who have played Tetris for a prolonged amount of time can find themselves thinking about ways different shapes in the real world can fit together, such as buildings on a street.
