A quote from the creator:
The software analyzes the image on your monitor and transfers its data by USB to the Lightpack board. This board lights the surface behind a monitor, TV or laptop by means of RGB LEDs of the corresponding colors. The effect reminds us of the illumination of Phillips Ambilight TVs most of all.
