Geeky Tattoos is a great photoblog of both geeky and nerdy tattoos, such as this Knuckles tat, worn by Henrique Barudi.
On occasion, I've thought about getting a tattoo. Maybe of a bear, like from the fantasy novel Shardik. Or just a Starfleet logo on my chest.
If you were to get a geeky tattoo, what would it be?
