On the 25th and 26th July 2015, I conducted Gen.AV 2, a 2-day hackathon on the topic of Interactive Computer-Generated Audiovisuals at EAVI, Goldsmiths, University of London. The participants developed tools for audiovisual performance, taking into account results from a previous workshop. The results are available here: github.com/avuis/, and the projects are presented in more detail here: www.gen-av.org/gen-av-2. The hackathon is part of the 2-year Enabling AVUIs research project being conducted at Goldsmiths. Conducted in collaboration with Music Hackspace (http://musichackspace.org). The projects were presented as public performance at Goldsmiths on the 30th July 2015.
