Nanotechnology art exhibitions provide more than a portal through which to enter the future world of nanotechnology. They also represent the state of nanotechnology in society today. This paper compares three exhibition forums that serve as representations of three of the most common genres of nanotechnology art (nanoart). These exhibition forums and their creators demonstrate distinct perspectives about what counts as engagement and how best to achieve it; they all attempt to persuade their publics that art can serve as a conduit for the creation of alternative nanofutures.
