Teachers in the author's graduate classes often say how much they would like to have a document camera in their classrooms. Since such a camera typically costs about $800, it is unlikely that many teachers will have their wish come true. In this column the author describes a simple solution: just make your own. He also looks at the issue of protecting yourself from spyware, which is a generic term for software that hides on your computer and records and sends information about what you do on it. Finally, he discusses one of the smallest and fastest Web browsers known, Firefox.
