Ideas not yet added:
i) music database system that remembers what you played. add mood tagging to music (which was tried by moodlogic in a different way) and suggest music based on past play.. interesting metadata that could be used to suggest music is past time of play, the weather at that time (weather.com or something), major news events (google news)
ii) interactive sculpture with touchscreens capable of video, that are miles apart connected via the net..
