Live Composer is a interactive music exploration application. Physical blocks (with fiduciary symbols) are moved around on a table and correlate to time and pitch. Moving the blocks creates a visual within a flash interface that notates and plays back the composition in real-time.

This application was a conjunction of Flash (for visuals), reactivision (for symbol tracking), and PureData (for dynamic audio).
