Two things:
1) Lisa Castaneda and Geoff Moore recently spoke at PAX East about teaching geometry with the Puzzle Maker. I love the idea of “broken levels,” where students have to finish building levels with certain restraints.
2) Here’s the data I used to analyze projectile motion, in case anyone ever wants to do their own data analysis: Portal 2 Position Time Data, Portal 2 Velocity Time Data.
Physics with Portals 
I was at the panel and loved it, but they mentioned the video of the panel would be online for those of us to show our higher-ups. Is that posted anywhere?
Just checked with Lisa. Unfortunately, she doesn’t know of any videos posted from her panel.
