Looking into it right now. I've asked this guy a few questions and he won't tell me anything about how they're made. I'm guessing an LED behind the needle... Of course he hasn't answered that one yet... I think since he's dancing around it, I may be close with my guess. I don't think I'll offer them for sale (no time), but a "How to" at the very least is in order if I figure it out...
