"Mouse Mischief integrates into Microsoft PowerPoint 2010 and Microsoft Office PowerPoint 2007, letting you insert questions, polls, and drawing activity slides into your lessons.
"Students can actively participate in these lessons by using their own mice to click, circle, cross out, or draw answers on the screen. "
This sound like a great tool to make your presentations interactive, get students attention and help them learn as you teach. Sorry--looks like Windows only.

It has been a HUGE week in EdTech this week with ISTE 2011, Google+, Microsoft 365 and the rumor of Facebook's big announcement next week (can someone say videochat)
"Transform your class presentation with video and images: A 5-minute makeover (video)"
Well, it takes a little longer to find the images and video that liven it up, but the helpful templates inside of PowerPoint can be used to much better effect than you might believe.
