A device (50) capable of selectively altering its appearance can include
a housing portion (64) of the device having at least one photochromic compound
and an ultraviolet light source (60) forming a portion of the device for
exposing the portion of the device having the photochromic compound to the ultraviolet
light source. A reaction by the photochromic compound can provide or serve as a
status indicator for the device. The device can be any number of devices such as
a portable communication device, a personal digital assistant, a laptop computer,
a camera, a GPS device, a printer, a camcorder, a vehicle, a toy, a personal hygiene
device, a watch, a calculator, and a writing instrument for example. The device
can be formed so that reactions by the photochromic compounds within the device
are controlled solely by the ultraviolet light sources (54 and 60)
within the device.
