Personal care device with illumination

A personal care device comprising:

• a main device body, comprising a plurality of light sources and a controller for controlling the light sources;
• and
• an attachment adapted to releasably couple to the main device body, wherein the attachment comprises:
• an attachment body;
• a plurality of light patterning portions integral with the attachment body, each light patterning portion arranged to receive light from at least one light input area of the body, and to provide a respective 3D illumination pattern within the attachment body when the respective light input area is illuminated, each light patterning portion being optically supplied by a different respective light input area;
• wherein at least a portion of the attachment body is formed of a light transmissible material, to permit each 3D illumination pattern to be visible to an observer at an exterior surface of the attachment body;
• wherein the main device body comprises a respective light source for each of the light input areas of the attachment, each light source arranged to optically interface with a respective light input area when the attachment is coupled to the main device body, and each light source being individually controllable by the controller;
• wherein the controller is adapted to implement a lighting scheme comprising dynamically controlling the light sources to produce a dynamically varying overall 3D illumination pattern within the attachment body.
