Right now I am working on a "Game with a Purpose" called MoodSwings. You can test this game at schubert.ece.drexel.edu/~lloyd/game.
I am currently setting up match play. I am also working on a music Search engine that searches the World Wide Web for music with lyrics matching your search terms. The short term goal of this project is to present the user with the song they are searching for, and allow them to label the mood via the MoodSwings. Because I am searching the entire web, I am not limited to any database of music, and can access anything within the public domain as well. This allows me to setup game play with content from sites such as youtube.
