I think I saw a video about a guy who made something like this himself once. It was pretty neat as he could navigate with his eyes closed and stuff like that!

Sounds interesting. Can you find it?
As a related note: considering the problems a magnet implant can cause you (as a person who recently had an MRI scan I'm quite happy I didn't get one), why not make something like Northpaw for sensing magnetism? Make it a ring that vibrates or a flexible wristband that contracts and expands in response to magnetic fields.
Sorry, I looked, but search results are polluted by Northpaw/Eric Boyd - it might have been the same guy though, maybe when he was prototyping. I remember someone doing blind figure-8s on their bike.
