Atheist Tattoo that is not offensive ?

I don't see the problem. Many people get tattoos to symbolize their faith, tattoos of Christ, crucifixes etc. and people don't get their panties in a twist over that. But I do see your point, you don't want to seem like you are slating religion at the same time as pointing out you don't follow a religion. But why does stating what YOU believe have to be offensive to someone else's believes in the same breath? It shouldn't.
