New technologies - YouTube

YouTube is just phenomenal for teaching. All it takes is borrowing a digital camera from media services, buying a mini-DV cassette, making a short film:
e.g. see below Dr. Ali Dinar speaking on the crisis in Darfur and targeting of civilians... an undergrad who knows how to use imovie (or learn yourself- it takes 30 minutes to learn the basics) and then you just post the video to YouTube in about 3 minutes. The benefit is that now the clip is easily available to embed in your blog (as I have done) but also to share with others (in fact, with practically the entire world- the community of Sudanese using YouTube, for example, is apparently enormous judging by the quantity and viewing of music videos from Sudan being posted). Imagine teaching a music class on Sudanese music and having 1000s of clips available.
