The way the monkey is holding the book reminded me of a bird in flight and led to this image of books as gulls. After selecting the book, the 'gulls' were created by first inverting the image (which produced the chrome appearance) and then using the liquify filter to shape the wings. Different sizes and orientations give some variety and depth to the flock. The wave is a modified stock photo with a hazy sun added with the lens flare filter.
