This post just links to a few Ruby videos I've found on Google Video that I hadn't seen before.
How to Design A Domain Specific Language with David Pollak. 1 hour 2 minutes. Slides easy to read, camera is close to projector. David kicks things off with a surprising answer to "What is the world's most popular programming language?" that grabbed my attention straight away.
Code Generation With Ruby with Jack Herrington. 50 minutes. Interestingly, a product manager from Google suggests Ruby will "in the long run" become "more and more popular here", which is good.
Ruby and Google Maps with Andre Lewis. 1 hour 2 minutes. Unfortunately the resolution isn't good enough to see any of the code he's working on and the camera is fixed.

Thanks for those...I liked David Pollack's, and I'm looking forward to Herrington's...I read some sample chapters of "Code Generation" about 3 years ago, and loved it.
