The fact is I have never had a design in mind that I liked long enough to get it stuck on my body. For a while I had the idea of a brain from the top, but upon careful reflection realized it would look like an ugly birthmark from a distance.
My calligraphy is also an option.. (see www.thunderwords.com for a gallery of my calligraphy work) The problem with this is two-fold. First, my style has changed over the years, though it has started to settle down. The second is that I don't know what word I'd want. One of my favorite words, "Rumpus," looks relatively bad in my calligraphy, because I have trouble with the letter "u."
I also had an idea of getting a tattoo of something REALLY trendy like Alf or "Where's the beef?" You know, something so monumentally stupid that nobody would think it wasn't a joke.
