CSS god Eric A. Meyer has created another amazing tool: S⁵ is a slide show system based entirely on XHTML, CSS and JavaScript. The slide shows work in all modern web browsers without requiring any special plugins, making them very easy to distribute. Sure, you do not get fancy fade-ins, but it has keyboard navigation (press space or cursor keys for the next slide) and most browsers can go full-screen, too. The whole slide show is contained in a single file, and if you know anything about HTML you can create slides with your favourite text editor. If you know something about CSS as well, you can tweak the style, if you do not, just use one of the available themes. Go see the introductory slide show!
