How to read a vacuum gauge

I stumbled on this site tonight. Vacuum gauges can tell you a WHOLE lot about your engine, IF you can read them. Most vacuum gauges come with directions about how to read them, but I've found those directions pretty confusing overall. This site helps enormously. At the bottom of the page is a little flash animation that shows exactly how the needle will move and what it means when it does. It's really helpful.
