Ricoh has announced the world's first commercially available spherical camera -- no, it isn't shaped like a sphere: It captures spherical photos that take in the entire scene, in a 360 degree arc around you, and also from floor to ceiling (or ground to sky). Called the Theta, the camera is capable of taking both spherical panoramas that can be viewed in a Flash applet or dedicated smartphone app, or the scene can be compressed down into a standalone one-dimensional image.
