There is a good chance that the campers of the future will be lighting up their campsites with the Leaf Lantern from Samuel Li. The Leaf Lantern is made up of small disks that produce their own light and can be stacked on top of one another.
The disks can either be used in the lantern mode or individually, letting you partition part of your lamp to light up darker areas of your campsite. Each "leaf" is solar-powered and the lamp is cordless, needing no juice whatsoever. Check out Samuel Li's Leaf Lantern here. I definitely think my disdain for camping would go down a notch or two if I was able to keep my campsite lit up at all hours of the night.
