The speech is called “Games as Instruments for Observing Our Universe”, given by Jonathan Blow at Champlain College in Burlington, Vermont in February 2010.

The talk is short — about 20 minutes — followed by about an hour Q&A (in a separate file). Slides in ppt format are included.

Here’s a bundle containing those files.

The next day, we did a conversational interview at the Firehouse Gallery in Burlington. This started with a short introduction about Braid and my next game, followed by some questions by Chris Thompson, and then questions from the audience. Here’s the audio for that session.
