Abstract: Systems, apparatuses, and methods are provided that include alterable characteristics and such alterable characteristics may be coordinated. Such systems, apparatuses, and methods may include wearable apparatuses and such alterable characteristics may relate to illumination conditions. In one example, a wearable apparatus includes an illumination device that may be manually manipulated between two different illumination conditions. In another example, two wearable apparatuses may each include an illumination device and operation of the two illumination devices may be coordinated. In a further example, operation of an apparatus may be controlled by a third party or venue. Still another exemplary system may include a capturing device for capturing a characteristic of an object and controlling an output device of an apparatus to operate with the same characteristic as the captured characteristic.
