Have one
Whelp - I have one that I did for a job interview presentation. It was done in Keynote 1, so you have to click everything (no timers). It's also not the frilliest thing in the world, as it was meant to look professional.
It's 8MB. I'm uploading it to my .Mac account for you, but I'm using a modem here. When it's up, I'll post a link.
You might want to take out some slides. Here's what it is:
Topic - discuss (in 45 minutes) the role of assessment in adult graduate and undergraduate education programs.
I took advantage of the Cube effect. It starts by traveling around the Assessment Cube as an introduction, then goes back around the cube with more detailed notes.
Still, most of the presentation was verbal, so there isn't a lot of text there for you to really know what I was talking about, but you'll get the general idea.
I'll post later with a link.
