How can I make a video recording of my computer screen?

TechSmith's Camtasia is a powerful tool for making a video of your computer screen, but it's expensive and more complex than most people need. There are a number of free alternatives that are simple to use, such as Screencast-O-Matic and Screenr. They work on both Mac and Windows, and don't even require you to download and install any software.
