Wow, this is one of those things that is just too weird to ignore. A teenager modified a laser-etching machine to give himself a Pac-Man tattoo. He disable the safety mechanism in the machine with a die and a magnet in order to get it to perform the job. It looks like it would hurt like hell but you can already imagine the implications and the ideas other people would get as to what they could have burned into them. I’ll pass on this one but it’s pretty interesting.
