Repetitive geometrical forms were dominant in soviet architecture and design. It seems that pavements / sidewalks were playgrounds for designers to try elaborate repetitive interlocking forms. Although interesting to explore, this repetitiveness, still dominating sidewalks all over the world, is unnatural, and ultimately creates an unpleasant feeling. That’s besides being unfriendly to small wheels of inline skates and skateboards, as well as high heels.
Here is a gallery of soviet pavement tiles from Armenia and Kyrgyzstan.
