Franco Bettonica and Mario Melocchi designed a very literal lightbox when they created Cuboluce. It's a small (4" x 4" x 4.5") box that lights up when opened. You can angle the reflection of the light by opening the lid a little more or a little less. Although this probably falls under the category of "decorative" rather than "task" lighting, I think it would work great atop a bureau or writing desk, on that hard-to-reach shelf that always seems to be in perpetual shadow. So for me it's a "mini task" light. Cost is $145.
