I'm always in for a unique way to recycle and reuse circuit boards, but usually the novelty look of the boards makes for something that's fun-looking, like this necklace, but not objectively cool-looking.
This Circuit Board Pencil Cup, however? Definitely an exception. Check out that color! The neon apple-y green is a refreshing hue that would brighten your whole desk area. And it's green in the other, more important way!
It's so hot it's sold out for now, but similar recycled computer goodies are available from the seller in the meantime.
