I’ve often thought about having a tattoo. Apart from the pain, the reason I’ve never got one is because what if after a year or two I don’t like it anymore. Yes you can have them removed these days but then there’s the added expense as well as scar tissue. So I’ve been toying with the idea of having some kind of augmented realty tattoo. Something that I could change on a whim or maybe for a giggle. Well, I think I’m now at the point where I can show the world the project. I’ve had a bar code tattooed on my right arm and using Processing I can scan it and display pretty much anything I want. so far I’m just displaying phrases. Obviously over time it will fade and hopefully I might get a bit of a tan but I can cater for that in the code.
