I bought some of those Endust wipes for electronics, and I must say, they do a fantastic job. Cleaning an LCD with Windex usually leaves a wierd purplish film which blurs the display. The Endust wipes left my LCD, CRT, and TV screen spotless. If you’re an electronics clean freak, you’ll probably want to get some.
Hey I was looking around and found an interactive tutorial type tool, essentially it takes screenshots while you do something and can convert it into a flash movie of sorts. It’s free and I thought it was kinda cool, thought you might be able to use it for any of your class type stuff. http://www.debugmode.com/wink/
I’ll give it a look-see. I need that for my teaching.
