Somebody over at Mosleymeetswilcox has a way with arts and crafts. They put some polystyrene balls together with some PETG plastic (nope, no idea what that is) and made "a seductive, lightweight material" that they then turned into the Nimbus.
The Nimbus is a ceiling light that looks like a gentle, puffy cloud. Mosleymeetswilcox describesitthisway: "As light passes through the gaps between the polystyrene balls it is reminiscent of sunlight shining through a cloud." Sweet!
The Nimbus is still in development so not officially for sale, but Mosleymeetswilcox does have an e-mail address on their site where you can inquire about buying one.
