There are a lot of strange things out there that we miss because they are just too small for us to see. Fortunately, there are microscopes out there to magnify them for us.
Offered for your consideration, the EIPBN 2007 Nanofabrication Bizarre/Beautiful Micrograph Contest, sponsored by Zyvex Labs (Note that there are a LOT of pictures on this page, so it may take a while to load). If you want to see the winners from previous contests going back as far as 1995, see this page. EIPBN stands for Electron, Ion and Photon Beam Technology and Nanofabrication, by the way.
