At the time of this writing, this news isn’t terribly new, but its new to us, so we thought we’d mention it.  The possibilities are actually pretty endless once you start thinking about it.

This U.S. Patent was actually issued on August 7, 2007, but it describes a device with a color calibrated monitor that can be adjusted down to the nanometer of the light spectrum.  This technology might work with any type of light emiting monitor, such as a computer or pda screen.  Using this technology, a prescribed regimen of color and/or light therapy could be administered anywhere.
