We've seen sun jars before, but now "Joe," who runs a Geek Gear store out of Etsy, has created a mason jar that emits sun- (red) or moon-colored (blue) light at the flick of a switch. It's battery powered, and so not as environmentally friendly as the solar version, but give the guy a break — it's made of a recycled jar. And it's customizable: if you're a werewolf and the blue freaks you out, you could toggle between red and green light-in-a-jar instead. — S.E. Kramer
