I've got a bunch 0f PowerPoint slide shows that I've gathered in my web-hunting over the years, but it has always been a bit of a pain to post them here. If you've been reading this site for long, you've seen me host some on a file-sharing site, but there is a delay for free downloads. Now I've found a site that allows free uploads and creates a file that can be embedded here. SlideShare.
Here's another slide show for you - cute photos of animals and people.
Note: You can view the slides full-screen by clicking on the little screen emblem in the lower-right control panel of the slide show.
