Have you ever wondered just what the wings of a cicada look like really close up? There's a company with a nifty piece of tech that can show you exactly that, and anything else, down to a micron level. Its fascinating computerised rig can be configured to capture the most detailed macro photos you've ever seen.
Using an off-the-shelf Canon EOS 600D and a macro lens (I'm guessing the MP-E 65mm), hooked up to a CNC-esque, 3D-printer-esque contraption, the Magnify2 moves across the X, Y and Z axes snapping photos and building a tiled photo that can be navigated a la Google Maps.
Since there's no camera on the market that can capture a single gigapixel image, building a huge multi-layered sheet of photos is the only way to get that granular level of detail. Wedding photographers have been using the Brenizer Method to capture high-res photos with thin depth of field for years; this system uses the same basic idea but moves the camera back and forth to capture as much depth info as possible.
