Concept: Glowing bookmark makes darkness obsolete

No need to light up the whole room when all you need to do is see the page in front of you. That's the idea behind Lightleaf, an elegant design concept that could be a solution to the problem of darkness.
We love these illustrations, even though this concept involves technology that's not quite practical yet. But really, who wouldn't want a foldable bookmark that's evenly illuminated by OLEDs, and powered by wireless induction charging? This is a design we're willing to wait five years for.
