If you don't find it first, I'll post the link later. It talks about creating custom default animations for a custom view. They show a simple example of a red rect path animation the stroke width.
Unfortunately asciiwwdc doesn't include the text of the PDFs associated with each video as far as I can tell and is just taking the transcript. The transcripts also are clearly automated (when provided by Apple as closed captions) and not always accurate. These things might hinder some searches. But even the PDFs don't include things like presenter notes and are sometimes very rough exports from Keynote.
