That sounds like an interesting idea, the flashing lights. The only thing I worry about before considering trying such a thing, is could it harm my eyes? I believe that this could not actually indcue REM sleep during the day, but it could make for great HI induction, which I would love, as I've never really experienced HI, and have heard it can be quite enjoyable.

p.s., how do I induce HI during the day, if I want to experience it for fun? I have heard that it is possible, and can induce some really cool, real images.
