This hangs on the wall and when it's lite it projects a larger shadow back on the wall. Cool effect.

The design of the lamp is very simple and unassuming, but the projection of the shadow is very pretty in a dark room.

The Lumen by Adam Frank is hands down the ideal gift for just about everyone--especially the person with everything. This New York artist's exploration of light and shadow has lead to performances, installations and this winsome alternative to an oil lamp--or yet another candle. The farther the lumen is from the wall, the larger the shadow from the acid-etched form. As the flame flickers, the soft shadow moves about organically. Frank's lumen is fashioned from a stainless steel body with a polyethylene base to prevent scratching sensitive surfaces. Comes with two 17-hour liquid wax fuel cells.

This steel oil lamp casts a shadow of a tree on your wall! There are three or four different trees/shadows to choose from, I like the one called "nest"

This lamp projects beautiful silhouettes of trees and birds onto the wall nearby. I particularly love the Flock pattern of seagulls.

This little oil lamp throws really amazing shadows on your wall, courtesy of tiny metal cutouts attached to the base. Want it to look like you live in a woodland paradise? Now you finally can do it, and for a lot less than it would cost to plant trees in your house (via Gizmodo)
