We have trees on the brain right now. Two reasons: the charming tree-themed show at Giant Robot Gallery, and an email we received the other day from a friend in NY. The hot weather has her locked up inside her apartment with the AC on for days on end, and the thing she says she misses most is "seeing trees." So the Lumen Lamp struck fertile ground. Adam Frank's oil lamp shadow projector brings the wonderful sensation of "seeing trees" inside, whether you're hiding from the daytime heat or simply relaxing at home at night. $59 at Generate.
