CyberSImps Improv Performance Event Stanford University's CyberSImps performance connected five theatrical improvisers at Stanford with four performers at UCLA for a live, distributed improv event. Interacting over low-latency, high-bandwidth audio and video streams, the improvisers created live scenes with performers more than 400 miles away. Over the course of the performance the group improvised several radio plays with voices from different stages and with live sound environments provided by UCLA's Visualization Portal. All of the scenes involved characters in both locations. In the spirit of an improv show, the audience was also asked for suggestions and audience volunteers were invited on stage to perform with the improvisers. Daniel Walling, a member of the SoundWIRE research group at the Stanford University Center for Computer Research in Music and Acoustics (CCRMA), directed CyberSImps as part of his honors research. According to Walling, "Transmission technologies prior to Internet2 have been unable to support the sensitive communication that enables theatrical improvisers to work together." The audio connection for CyberSImps was supported by the StreamBD software, created by the SoundWIRE research group at CCRMA; the video was supported by OpenMash. SoundWIRE receives funding and support from the National Science Foundation.
