RjDj is a music application for the Iphone. It uses sensory input to generate and control music you are listening to. RjDj is mainly consumed with headphones. Think of it as the next generation of walkman or mp3 player. The consumer experience of RjDj is similar to the effects of drugs. Drugs affect our sensory perception, so does RjDj. RjDj is a mind twisting hearing sensation.  (Damage sez: will buy new iPhone just for this.)
