Given that Tetris is the ultimate "building stuff out of blocks" game, it's probably no surprise that it has architectural analogues. Here is a gallery of buildings around the world that look they were built by crazy Tetris fans.

This model community in Montreal, Canada was built for the 1967 World's Fair. It has 146 residences, (354 concrete forms in 12 storeys) all of them with a private terrace.
