If you couldn't tell already, we here at Neatorama love Star Trek, whether it be the original, the Next Generation, Voyager or Enterprise (some of us even like the new reboot, though that's a hotly contested subject). No matter what version of the show is everyone's favorite though, you have to appreciate the original for kicking off the franchise and with that in mind, we adore Leonard Nimoy and these strange art tributes to Spock are something even those with only a mild interest in the U.S.S. Enterprise can still appreciate.
I'm a particularly big fan of his emo look, though he also makes a pretty great centaur.
