Jordi Parra's Spotify "radio"
Sweet!! Spotify player using RFID tags as physical objects to store Spotify playlists that the "radio" can then play... is Jordi Parra’s degree project.
Lovely example of humanising tech.
Also a nice moment to mention IDEO's similar (and similarly awesome) project c60 Redux - which does a very similar thing but using specific tags for music files rather than playlists.
