Here is a good idea made just right. The Lumen Tree by Adam Frank is an oil lamp that projects the shadow of a tree onto your wall. The tree and the body of the lamp are made of acid-etched stainless steel, and (this is cool) the flame comes from a 17-hour liquid wax fuel cell, which is both odorless and clean-burning. As the flame flickers, the shadow moves naturally, and – if you’ve forgotten elementary math – the farther away from the wall you place the lamp, the larger the shadow will be.
very nice. I’d like to see a tealight version though for cheaper $$
