I've always been far too fickle to get a tatoo. I change desktop wallpapers every couple of days.
However, last time we did a round of interviews for a design position every. single. candidate. had either a visible tatoo or peircing. I had no discrimination one way or the other, if anything, I was feeling left out
We've a designer here right now with the most awesome sleeves I think I've ever seen IRL.
Just to echo what's been said above; it's a creative industry and creative people are, by and large, not normal - and that's why I love them and this industry
