Building on my earlier posts (below), an interesting application at OUseful Info.
Extending UC Berkeley's YouTube Site:
I was intrigued as to whether it's possible to search videos by user on YouTube and get the result via a feed using the YouTube/GData API, and it's easy... For example: http://gdata.youtube.com/feeds/videos?q=skeletal+biology&author=ucberkeley.
Using a simple bit of GrazrScript, it doesn't take much to build a little search widget around this feed, that you could then embed in your own page.
To make things a little more interesting, though, I also added a feed embellishment via a Yahoo Pipe that adds the movie as an enclosure to the feed so that it can be played directly within the Grazr widget (scroll down on the result in the widget... the embedded player may look a little broken at first, but it works fine if you click on it).
So here it is: UCB Video search via Grazr
