Tattoos are currently in a weird place, in my opinion. You have your tattoo gun, you tattoo a permanent thing onto someone's @naked's, and that is that. It's great, tattoos are cool, but what isn't cool is spam. As the current coded system goes, if you want to describe what the tattoo looks like, every single word tacks onto the length of someone's @naked, increasing the length of their description by a vast amount.
I had an idea, that was shot down, about using a clothing object to create a 'tattoo'. You'd still RP using the tattoo gun and what not, and have the @worn message be quite short, while having the description be as detailed as you like. That way someone could 'look tattoo on person' and see what the tattoo really looked like. I can't really go into detail on why the idea was shut down, because apparently it would require extra coding of some kind to properly implement. (ideas of why this doesn't work in a decent way in game is because clothing objects have a weight, a value, can be removed, can be sold, can get bloodied up....possibly other effects that I'm not aware of)
I think the base idea of it is exceptionally better than the one that is in place at the moment.
Create a describable tattoo, with a short @naked description, so people can have all the detail they could ever want, without forcing the huge amount of details on everyone that just wants a refresher on what color eyes someone has for their RP.
