I can't really sum up everything I've seen. It's just too much! From highly detailed talks on the making of UP, to learning all about story development, the electronic theater screening (which is the best of the best animations and technical papers here at SIGGRAPH), emerging technologies, the art gallery, job fair, how to plan a short film, patch-based image vectorization with automatic curvilinear feature alignment and approximating subdivision surfaces with Gregory patches for hardware tessellation. Just kidding about those last two! I have no idea what they are, but those are some of the extremely advanced technical paper's names. Intense!
Anywho, I'll just let the pictures do the talking from here. Enjoy and if you have a question about one, just ask!
