My wife and I want to get tattoos. I've always wanted one, but always struggled with what to get.

I almost got a bicycle sprocket/chainring bent into an infinity symbol back when I was racing mountain bikes a lot. I've since got out of the sport, so the 'infinity' wouldn't be too appropriate any more :)

Anyway, what good coder / programmer / general geek tattoos do you have, or have you seen? Give me some inspiration here!

This is a formula called the Y Combinator. It is a fixed-point combinator in the lambda calculus and was discovered by Haskell Curry, a rather prolific mathematician and logician whose work helped start Computer Science.

For more geeky/science related tattoos check out the Science Tattoo Emporium.

I grew up in a naval town, so I have seen a few tattoos. IMHO it doesn't matter what the tattoo is, because they will all look like crap in 20 years time. Make sure you factor that into your decision.

I have a tattoo on my left arm in binary. It says NERD:

I saw a picture of a guy with a barcode on his neck. I've never seen any real code related tattoos. But almost anything you do is going to be obsolete in a few years. I'd stick with something written in binary.

I always thought electron orbitals would be rather neat.
