m3Dcam allows users to create 3D (anaglyph) photos. These photos can be shared with others by uploading to www.m3dcam.com. Special anaglyph (red-cyan filtered) glasses are needed to view the 3D photos. Download (m3dcam-v2-u.jar - unsigned version) if you have trouble installing the application (this applies particulary if you're from the U.S. or China).
