I'm sick of using library receipts as bookmarks. I could buy one, but it kind of seems like a waste of money. Not so with the Bookmark lamp. It provides two useful functions.
The only problem is that it is only a concept at this point. Then again, anyone could make one of these in a matter of minutes. It's just a good, simple idea. [Designboom via Likecool via Coolest Gadgets]
