I'm sure that at least some of you have done your fair share of modding, but how many of you have been to prison? Apparently inmates just love the N64 rumble packs.
Apparently it isn't that difficult to fashion your own homemade tattoo kit by using an old rumble pack and a couple of other everyday items like an ink pen. You just take out the motor, wire up a battery and attach a needle or pin to it and presto! You can tattoo all day and night.
Mind you, this is not one mod that I would ever suggest that you perform yourself. There's that whole issue with needles and disease and such.
