A lamp that produces an infinitely variable range of time, space, and color patterns. The lamp includes a plurality of colored light sources that produce light in at least two different visual spectrums, a single modulation device that generates a modulation scheme for each of the plurality of light sources, a display screen, and a mask that masks off at least a portion of light illuminating the display screen. The generated modulation scheme is produced at a predefined intensity level. A controller selectively alters delivery of the modulation scheme to each of the plurality of light sources. A first switch allows a user to select one of a plurality of modulation schemes. A second switch allows a user to alter the predefined intensity level. A third switch allows a user to select one of a plurality of modulation rates.
