My lecture at GDC about my Locomotion System went really well I think. I've had some requests for the slides, and they're available here:
Dynamic Walking with Semi-Procedural Animation (PDF, 16 MB)
Note that the presentation included quite a few videos which are not in the above slides, so a few points may not come properly across if you did not see the presentation at GDC.
GDC may at some point make a recording of the slides available, complete with audio. I don't know if that would also include the videos I presented. I'm not so sure of the details. If anybody finds out, please let me know!
