The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. The apparatus can be tuned to an onoff state or transmitreflect electromagnetic energy in any frequency. Responsive to executing the second code in the second node, the second node establishes a communication channel with a third node, replicates itself to generate third code, and provides the third code to the third node over the communication channel. A corresponding plurality of optical output devices is disposed proximate the output element, wherein each of the plurality of optical output devices receives a corresponding single, multiplexed, polychromatic optical beam. The near-distance is preferably one half of the far-distance but may be longer or shorter than the far-distance.
