The recent use of streaming video on the World Wide Web for the distribution of live images has enabled an interface that supports a new phenomenon of virtual, defered, remote presence, extending perception and expanding the possibilities of remote interaction. The purpose of this essay is to provide a brief survey of the use of these live images in artistic spaces specifically conceived for this medium. These environments will be presented in three different categories, which propose transformations in possibilities of participation, interference, and the participants' self-expression.
