I was lurking on the Fred Miranda Macro forum today and came across gentleman by the name of Frans that has the most amazing gallery–3D macro. You need to look at the images cross-eyed for the effect to work, but when you get it–coolest thing ever.
Frans also developed a system for taking macro photographs of insects in flight. Using the rig, he apparently gets a beastly-high percentage of in-focus images. I’ve just started exploring his photographs, but what I’ve seen so far is really pretty amazing; especially if you have any idea how hard it is to take macro images of insects that are flying around. At the very least, check out his 3D galleries–you will not be disappointed.
