whats this style of art called? i had a dream i saw something like this painted on a large brick building it was clearly a city skyline in the dream and didn't look so 3d-ish lucky it was just made of shapes so i could sort of re-create it. it looked like several city skylines of bright elementary colors overlapping eachother but composed of the same sqaure-triangle shape. in the dream it very impressive if i spent more time on it could have made something better. the effect made it look like a huge metropolis and it was simple enough for construction workers to produce them on a building with basic template
