No tattoos at the moment. Still illegal for me as of yet.
If I were to get any tattoo at all, I would want it to have significance in the first. Not a cheesy print of a certain (ex?) girlfriend's favorite chemical compound, but a botanical specimen with historical and floriographical significance or an alchemical symbol with significance. An anatomical diagram of a heart over the chest would be classy.
I'm rather fond of the symbols for silver and for preservation/purification by fire until white hot.
Edit: for clarification, yes I want a cool tattoo.
Secondary edit: cheesy print of ex's fav chemical compound would kill me inside
