Liveplasma is a great service that visualizes music or movies based on a given band, movie, director or actor. This is the visualization I got when entering 'Matrix' and searched for similar movies:
A nice way to customize and get recommendations by means of personalization. Personalization can support mass customization to get better fitting goods at low (transaction) costs (Piller, 2003). It even works without personal information, but that leaves personal recommendations out. I'll try it out for some time!
