The "Active enclosure for computing device" features embedded LEDs that can be used to change the color of the computer housing. Dubbed a "chameleonic electronic device," the patent notes that the casing and multicolor LEDs could be uniquely positioned or the intensities changed to vary coloration, create an outward design (spots/stripes), make a portion of the housing "glow" or simply light the outline of the casing itself.
