Design and Technology at Siggraph 2007

From 5-9 August, over 24000 artists, designers, research scientists, developers, filmmakers, and academics gathered in San Diego, California, for the 34th Siggraph Conference on Computer Graphics and Interactive Techniques. The Siggraph conference and exhibition ranges from several days of highly technical courses and academic paper presentations, through to hands-on demos of new technologies, an art gallery, computer animation festival, and the two-day exhibition by software and hardware vendors. Siggraph straddles the scientific, engineering and the artistic aspects of computer graphics and interaction, with film-makers showing how they made "Giant Frickin' Robots" for the upcoming Transformers movie, while the Papers presentations and Courses deal with the latest research, software evolution and hardware systems that make it all possible.

Wisconsin is sitting on massive deposits, too -- of cheese brine.
