This wall mounted artwork contains 180 LEDs in a grid behind diffused white acrylic.  It is framed in black aluminum.  When the red button is pressed on the box below, the whole color field turns red.  The color then changes to green, then blue and on through other colors.  Each LED changes at a slightly different rate such that they all fall out of phase and "entropy increases".  It reaches saturation within about 2 minutes.  At this point the whole field is constantly changing color, but it is so subtle that you don't realize it at first.  Then you are drawn in to watch the color shifts close up.  It is hypnotic.
