Wentworth (on the tattoo evolving for Prison Break): Okay, the dirty little secret is that the tattoo is still evolving. It's design isn't set in stone. The tattoo tends to change based on changes to the production schedule and sometimes a plot will shift. There's a particular episode where Michael references a few names and if those names don't get cleared by the Fox legal department they actually have to change one of the names. So the tattoo is in a constant state of flux.
