Origami Lamp Folded From a Single Sheet of Metal  This lamp
comes as a flat metal sheet with perforated fold lines, and
someone can assemble it in a few minutes without any tools. It's
coated with a special paint that's designed to resist any
cracking when it bends. Like any flat-pack product, this can
save a lot of space during transportation, and consequently save
energy; the more products can stack into one container, the less
gas it takes to move any one of them around. This design is
particularly impressive since it's so flat.
