I don't currently have a tattoo (largely because I'm a needle-phobe), but I've seen a lot of beautiful ink. I've thought about getting a small water lily, styled after Japanese print work, both because I love the art and because "Lily" is my daughter's name.
In most cases, I think that ink can be really beautiful if done by a skillful artist. I've seen some beautiful Yakuza-style body work that's made me think "pretty," but I also know that I don't have the personality to pull it off. (One of my undergrads a few years back had a beautiful Yakuza-esque sleeve.) On the other hand, I've got a next-door neighbor with Aryan Brother/skinhead tats that make me think, wow, this guy's a loser. But it isn't the ink that makes him so. I've also seen high school kids who've gotten ink who probably didn't think a whole lot about them, but even if they turn out to be a regret later in life, who among us hasn't done something stupid as a teenager?
