This guy is printing out SimCity 2000 cities with his 3d printer. Very cool. Check it out:
"All these building where modeled in Google Sketch-Up based on my memories of playing Sim City 2000. (Still my favorite computer game of all time). This is an ongoing effort. I model these buildings when I am in-between projects and need something to clear my head. Expect more buildings to be added to this thing as time goes on."
More 3d printed SimCity buildings by others in the gallery.
