From Polar Inertia:
"For the most part Soviet architecture and design is remembered for its heavy block buildings and functionally Spartan designs. Its overpowering desire for conformity left little room for individual creative freedom. A notable exceptions to this is in the transportation sector. One can admire this creativity in the Metro stations of cities like Moscow and Tashkent where the coldness and sterility of typical soviet urban architecture is abandoned and costs are not spared as creative freedom is unleashed. While many of us are aware of the elaborate splendor of the Moscow underground, it is easy to overlook the phenomenon of the common roadside bus stop as an example of soviet art and design letting loose and becoming a little weird and crazy."
