Changing is an interactive video installation piece by new media artist and teacher, David Gladden. The video is a mix of live feed camera, archival footage from the Prelinger Archives, and video footage shot by the artist.  Significantly, this installation uses a custom-made software application created by the artist. The application runs on Macintosh computers and is named GladFXPro1.  Changing was exhibited at Salisbury University's Fulton Gallery as part of the faculty exhibition 2014.

Above is an example of the custom made application that was created specifically for this installation.
