Meet the NECLUMI: a projection-based necklace that relies on an app and a projector to provide you with an interactive experience. At the moment, the setup relies on an iPhone running an app and a Pico projector to work, so it is a work in progress. The necklace reacts as the wearer rotates or moves his/her body. The idea sounds interesting, but will interactive necklaces become a thing in the future? We will have to wait and see.
