During a residency in 2005 with Het Productiehuis at the Rotterdam Schouwburg, new technological configurations were tested in a test show 'U_n'. The big difference in the configuration with the predecessor CRASH is the mobility of the spectator. Walking through the virtual image he feels physically 'there'.
The immersive performance takes one spectator at a time. Once encapsulated in the technology the borders between reality and virutality, time and space, fade. The computer, omnidirectional cameras, and immersive video take control of and manipulate the senses.
