Do you know how many times I've wished for a bookshelf that also does duty as a bookmark and a reading light? To be truthful it's zero, but if I had, it seems the folks at Studio Smeets have already taken care of it. Their clever little design is called Lili Lite, and it has a sensor that turns on a light when an open book is taken off the shelf and turns it off when a book is replaced (you can also turn it on/off manually if you feel like burning a few calories). It's attractive enough - I do like the shelf - but the light itself reminds me a bit of a Macbook power cord chopped in half.
