For the idog team:

Preliminary design notes:

on adapting the Idog music player to play music so the the beat/min rate is proportional to the level of indoor pollutants (which specifically is yet to be specified, depending on the measurability and what contaminants are of local concern).

To solve: notes on controlling a music player--adding beats/min(bpm) info to music library such as itunes, and how to talk to itunes(or other software to select tracks on the basis of this.
