Professor Arthur J. Olson of Scripps demonstrates a 3D printed model of a virus that self assembles when shaken. Olson is head of the Molecular Graphics Laboratory, which uses 3D computer models, 3D printing, and augmented reality to create tools for life science researchers and educators. He is also the project leader of Fight Aids at Home, a tool that allows home computer users to share their resources as part of a massive project to find new HIV drugs.
