We found this seemingly invisible shelf over at Popgadget. By attaching the "shelf" (it's that bottom look-alike book) to the wall with a hidden bracket, your books will look elevated in a whole new way. Buyers have a choice of khaki, red, or turquoise spines, but what we'd really like is a choice of book title and author...does it really have to say "S.E.L.F. Shelf" on there?!
This intriguing product is available for $29.95 from Firebox, with a 9 lb. weight capacity.
