Perforce Multimedia library
Documentation, documentation, documentation - all text and no pictures? Well, no - the product pages have slideshows for some of the products, but that's really just intended for people who are seeing them for the first time.
So what's there for existing/new users who want a good visual walkthrough or tutorial? Well, my coworker Brian Holtcamp has been steadily adding topical Flash videos (and some audio) to our media library. We've got topics ranging from "Workspace Concepts and Setup in P4V" to "The Flow of Change". They range in duration from five minutes to an hour, with most being under ten, so you should be able to go through them pretty fast.
If you have comments, ideas for new topics, etc - please let us know! (by sending an email to multimedia @ perforce dot com!)
