Very nice tattoo. I have a similar pattern on my travel hubbly box that I designed myself.

I had to go look for the photo. Each side of the box got a differant pattern.

Looks fantastic. I like op-art a lot, I had an occasion to visit Victor Vasarely exhibition last year and see his genial graphic works. It's hard to believe that he didn't use computers. And op-art tattoo is very good idea.
