Since Im kinda of neutral on tattoos, and dont really see the need of em, My opinion dosn't count.
But since this is the internet, which is all about giving your opinion that no one asked you for, Ill give it anyway :-D
I have yet to see anything SOO spectacular in my entire life, to have the urge to want to permantly "fuze" it to my skin. (With the exception of my reflection, but you know... cant fuze my face can I? :-D ). Honestly I don't think there is anything on this earth... with the exception of a 3D render that would look so good, and to create a copy on my skin so I can see it whenever I want. So until you can render your skin, I find tatoos pointless :-D
