We always see hidden doors hidden in book shelves, opened with the pull of one volume. What about integrating other designs into book shelves? This Book Collection Clock is a cool way to integrate a time device right in your book collection, while making people make a “huh?” sound as they pass.

The numbers “Nine” and “Three” appear to be the titles of the two outer books, though actually stand for the numbers they represent. I wonder what they would say if I were to return this to the library by accident. Get your own for $24.95. — Andrew Dobrow
