posted about the Airswitch TC back in November last year, but we just read that there is another version that is out now. Airswitch lamps, by Mathmos, change with movement. If you raise your hand above the fixture, it brightens, and if you lower your hand, it dims the light. The Airswitch 1 is a cool frosted white edition that looks like a science lab flask.
It's available at Zipper on 3rd Street. ($84)
