Google maps 8bit quest mode.  A setup for 4/1 perhaps?
Interesting, if you look at Pyongyang (North Korea), it has a bunch of labels that don't show if you use their regular maps. They're quite detailed too, it shows "Statue 2 of 'The Newly Freed Proletariat Thanks To The Grat Leader Kim Il-Sung'", schools and such. They must have hidden map data they don't show normally that leaked into this map.  http://g.co/maps/tg9jy
