I've found this adapted lamp in the latest Elle Decor (UK edition). It belongs to Australian fashion designer Martin Grant, who lives in an absolutely gorgeous (but not too ostentatious) apartment in Paris. Back to the lamp, the original idea is that the water magnifies, and the light source above (a candle in its original 19th century state), illuminates. I found this lamp very ingenious and aesthetically pleasing. Oh, and the whole flat was a-ma-zing.
