There's something really meditative about these slotted lamps. They're made out of wood from California cypress trees and the light inside is a constant current LED, but the sculptural elements come through more than the utility as a lamp.
Designed by Paul Foeckler for Split Grain in LA, the lamps range from $US750 to $US1950. They may not be on your IKEA shopping list, but each one requires about 100 hours of slicing and sanding so... yeah. Oh, and the smaller lamp is USB powered by computer or wall charger for some reason. Nifty. [Etsy via Colossal]
