Anaglyphic imaging is the century old technique of displaying stereoscopic images using color separation to be viewed through specially colored glasses. In an anaglyph, two colors are used, red (for the left eye) and blue (for the right eye). The mutually exclusive colors allow each eye to see a different perspective, forcing the viewer to merge the two through variable depth focus.         More information on the node and it's variations can be found within the Life of the Node series of Levitated Expansions.     jtarbell, July 2002
