These pictures may look like ghostly illustrations, but the are in fact painstakingly-constructed photographs. Barcelona-based artist Max de Esteban disassembled various gadgets, photographed each part individually and then combined these photos to make an x-ray-like composite.
The results look like the illustrations inside the how-it-works books I loved as a kid, only instead of being airbrushed paintings, they're totally accurate, real representations.
If you want to see the full-sized versions, you'll need to head over to Max's current exhibition in Brooklyn, New York (the launch party takes place tonight). Or you can check out the photos at the Klompching Gallery's site.
