Slides are sparse, because we were all given only 20 minutes to speak!

The report is particularly interesting: http://sfd.beijinglug.org/report.php
"We really want to thank the speakers who have come from as far as Australia (Colin Charles) and Taiwan (Jollen and Chelsea) or Lanzhou (Pr. Zhou) or Liaoning (Blender team) in China to share that special feeling with us. They have also focused their message on our specific topic which made it so compelling that people stayed up until the end (we finished one hour late, at 18:30)."
