MAKE Instructable group member VIRON made these DIY “Flash nap” glasses. I’ve tried glasses like these before and they never did anything for me, but if you’re curious – you can make your own. Seems like a fun project no matter what… – “This is basically the Flash Nap project with a few extra features and some work. It’s also a minimal version of “Light/Sound” hypnosis machines that cost hundreds of dollars, but if you have parts, this one will cost just a couple of bucks…” – Link.
