Guten tag! We spotted this lamp over at Decor8, and had to do more research. A quick call to one of our Berlin friends, and here's the poop: Impressionen is Germany's version of Anthropologie, what with the homewares and the clothes, and everything's available to be ordered. But back to this Bubble Lamp (aka "Tischleuchte"): one flick of the switch, and the cascading glass bubbles light up.
And while we may not be able to get one of these lamps stateside, we do have some alternatives, kind of. CB2's whirly gig votive candleholder might not light up with a switch, but the effect is pretty damn close.
