ACM multimedia interactive art program: an introduction to the presence/absence exhibition.

The second ACM Multimedia Art program followed the successful formula used in ACM MM 2005, consisting of a session of long papers, a selection of posters and an art exhibition of multimedia works displayed at a gallery for a period encompassing the conference duration. "Presence/Absence" was selected as the central theme for the exhibition. In this paper, we discuss our motivations in organizing an art program at ACM MM, the exhibition theme, the works selected, and their potential impact in the technical community.
