Many people mentioned the April 1st prank by Google: 8-bit maps, and a NES Google Maps cartridge (quote at 0:55: blow on the cartridge to fix bugs ROFL!)
Today Google Maps has a quest mode, rendering the maps in Nintendo NES “quality”.
Few people really used it, and missed the glorious 8-bit streetview, and the really nice landmarks that you see when you zoom in to a scale of 500 meter or better.
You can even link to the 8-bit maps and to the 8-bit street view!.
