I am big fun of special types of photography.
I like panorama photos and also anaglyph (3 dimensional or stereo photography). For viewing of this anaglyph photos, you should use special types of glasses. This glasses has left eye red color and right eye cyan color. When you use this glasses you will see third dimension. This is absolutely great. Few months ago, I started with spherical panorama. Service panoramio.com is not so useful for spherical panorama. If you want, you can see my spherical panoramas on site http://www.360cities.net/profile/miroslavolesnanik
I also tried to do much bigger photos, bigger than 100 megapixels. Some of them are published here http://gigapan.org/viewProfile.php?userid=13825
