One interesting case of design oriented wearable prototypes was a set of spatial jewellery created for the hostesses of a large party. The location-indicating jewellery, called Partydotcom, would shine a light on the ceiling, giving the location of the hostess. The prototypes were built with a specific use and intention in mind.
I created the electronics, while Petra Ahde designed the jewelry.
