Okay, so I don't know how this can't be like one of the coolest things ever! I would total put these outside of my house if I had to the money to waste. Think about being out of a country back road and you see a glowing driveway... That would be kinda creepy. Maybe a witch lives there. Ha ha. Anyway still awesome. There called Glow Stones and you can find them on DudeIWantThat.com .
