If you like this, you should also check out Ebb, a DSL for physical simulation built on Terra: http://ebblang.org/

Both were presented back to back at SIGGRAPH this year.

Are the videos available on Youtube?

Only a few sessions are available. http://s2016.siggraph.org/live-streaming-sessions

BTW, ACM had fairly strict no photography policies this year. Authors clearly put up content on their slides that were supposed to be photographed liked URLs and QR codes, but volunteers went around telling people not to. I'm not sure if ACM failed to make the policy clear to authors or if they overstepped on copyright claims.
