LightLeafs is an illuminated OLED bookmark by designer Valentina Trimani that provides just enough light for reading in the dark. The light is as thin as a page in a book and runs wirelessly. The designer states that the light could be rechargeable with brightness controls to turn it down so that it won’t bother others nearby.
Lightleafs is ideal for reading in bed but it can also come in handy when one needs to read a map in the car, or in the event of a power outtage. The form of the light is as minimal as possible, consisting only of a single piece that is easily stored inside your favourite book. It could conceivably double as a bookmark.
