Tom has been calling his master set of PowerPoint slides the "Re-imagine!500," but it grew and grew to over 1000 slides. Also, this summer he's had a chance to look at it, re-assess it, add to it, reorganize it. It's now re-issued as the "Re-imagine!Master." You can download it here. (Note: It takes a while—it's very large.) Or, you can get just the latest additions here.
