lightwedge.

Somebody had a bright idea when they came up with the Lightwedge. It's a reading light for books made out of a sheet of optical-grade (whatever that means) acrylic and illuminated by LEDs. The LEDs light the acrylic which in turn evenly lights the entire page you're reading. This seems like a better idea than traditional book lights, which tend to brightly light one spot of the page only.
