The Empty Air
The Empty Air is an experimental music installation by The Mural and The Mint. A musical score ebbs and flows depending on the user's location within Rittenhouse Square Park, Philadelphia.
Because it is the first of it's kind, this app was designed to have very minimal interaction, encouraging the user to put away their phone and experience the music while simply taking a walk.

Designed and built at P'unk Ave in 2013.
