• Vuvox is one of my favorite tools because it produces something so different from other tools. I have used it for a few presentations (e.g. http://www.vuvox.com/collage/detail/32318), and it was effective for using a variety of media that I could also provide annotations and external links. A few years ago the site was less reliable, but it has since been bought by eBay and seems more stable. - cogdog cogdog Apr 8, 2011
