Isadora is an award-winning, graphic programming environment for Macintosh and Windows that provides interactive control over digital media, with special emphasis on the real-time manipulation of digital video. Because every performance or installation is unique, Isadora was designed not to be a "plug and play" program, but instead to offer building blocks that can be linked together in nearly unlimited ways, allowing you to follow your artistic impulse. Isadora was initially created to realize the performances of Troika Ranch, a media intensive dance company co-directed by Isadora's creator, composer and media-artist Mark Coniglio. Isadora reflects over 20 years of practical experience with realtime interaction.
