One idea that really wows teachers whom I've worked with is using the digital camera and PhotoJam from Shockwave to create a slide show that you can show on either a screen with a projector or on a TV if someone has a scan converter. It creates a slideshow with music and special effects that is really cool! It was an easy way to really energize some reluctant teachers that I know of! You can download a free version of the program at Shockwave.com.
