Turn away the typical oil on canvas art work for something a bit more interesting. Adam Frank
created this series of acid-etched, stainless steel, oil lamp shadow projectors, which he dubbed LUMEN.
Since this is powered by a liquid was fuel cell, you will need to replace it when the oil is gone. Thankfully, LUMEN comes with two liquid wax fuel cells in the box, for about 37 hours of beauty. You can buy replenishment on the designers' web site ($6.00 for a pack of two).
Each Lumen retails for $48.00.
