The good people of Etsy are never short on creativity, but being able to produce something as stylish and eco-friendly as these recycled Ink Cartridge Hanging Lamps ($45) takes some serious skills. Made from four disassembled Epson ink cartridges (of varying colors, natch), these lights are a brilliant example of recycling savvy that also preform a basic function — lighting your room. Best part? You can customize the colors when you order to get the exact look you want. I'd love to hang a few of these from the ceiling of my office, or heck, even my living room. Let's not pretend — I like to wave my geek flag pretty proudly.
