Lightleaf: The Illuminated Bookmark

This is a great concept - a thin, illuminated OLED bookmark. It would be so useful, and I love its minimalist design. It would also have fantastic features - it'd be wireless, rechargeable, and it'd have adjustable brightness (smart, very smart).

It's called Lightleaf, and credit for it goes to Valentina Trimani. You can check out the site for the concept here.
