Methods and apparatus, including computer program products, implementing and using techniques for providing a computer peripheral including one or more keys. Each key has several light emitting diodes disposed on a face of the key. Each of the light emitting diodes can switch on or off in response to a data signal received from an application specific integrated circuit dedicated to the key. A corresponding key and manufacturing method, as well as a computer system including one or more such keys are also described.
