I think that Brasilia has a similar system, but the blocks themselves are somewhat different from blocks in normal cities. Take a look here for instance http://maps.google.com/?ie=UTF8&ll=-15.807925,-47.894082&spn=0.012223,0.022745&t=h&z=16 http://maps.google.com/?ie=UTF8&ll=-15.807925,-47.894082...
