Anaglyphs are stereo 3D images produced by merging a left and right picture of a scene. To view anaglyph images you'll need a pair of red-cyan glasses, but older red-blue ones will work too, but just not as well. You'll also get the best results by viewing these images on LCD displays. The phosphors on CRT monitors are extremely impure which causes anaglyph images to be very ghosty and sometimes not visible at all.
The anaglyphs on this site have been specifically tuned for Apple LCD displays, and we have special anaglyph glasses which are specifically calibrated for use with Apple Macintosh LCD displays. You can purchase these 3D glasses directly from the manufacturer for just $5 for two pairs.
