OOPSLA demonstrations provide an opportunity for companies and universities to show their latest work to an experienced audience. This can be work in progress, commercial applications, proof of concepts, results of academic research, tools, systems or any topic that has interesting object-oriented aspects. Demonstrations are not focused on selling a product but to highlight, explain and present the technical aspects of it. Demonstrators may actively solicit feedback from the usually very technically savvy audience. In the past, this has made for some very interesting demonstration sessions.
