Killing the Walk Monster

Remastered version of my BICFest 2018 talk about how the collision system of The Witness was engineered to prevent entire classes of bugs normally found in game engines of its type.
The original talk recording was essentially useless because the audio was corrupted. This version has been resurrected from video and audio recordings I had made for the simultaneous translators to use. I'd forgotten they existed, but thankfully rediscovered them recently.
