I was really intrigued by Lauren McCarthy and Kyle McDonald's "How We Act Together," both by the interaction between individuals and between computer and individual. The project shows you a stream of different pictures of other people interacting with the project from before, as long as you continue acting certain facial movements. It explores modern interaction, in both positive and negative ways.
I think it's interesting that it attempts to pose these questions about modern interaction, which involves lots of virtual interaction, through virtual interaction itself, with very distant people. The whole set up itself is already "awkward and intimate" and it's cool that they chose to accentuate that with a kind of interaction that induces a bodily response.
