Seriously tho....picture laying out a map of the earth flat on a piece of paper...then if you had a cookie cutter that spelled out "computer planet", and used it to cut out of the map. Know what I am saying ...make it so the map is in the letters? I dunno that seems like a real quick simplistic idea....easy to do to...hell I think I could even do it.
Although it probably wouldn't look that cool or anything.
Or another simplistic idea would be to have computer planet circling the earth...like a ring, maybe in a retro kinda way. Ever seen those old news braodcasts where the broadcast companies name would circle around the planet w/ a cheesy transmiter at the top of it, and little broadcast waves emanating out of it.
