Tired of using Powerpoint or OpenOffice Impress just to make a presentation ? Sometimes I just want to create a slideshow which 'just looks good', without having to find out all hidden options in a presentation software. If you have the same opinion, you might want to try out S5, a webbased slideshow format, consisting of one html file, and some CSS markups. Very interesting if you have to give presentations on computers other than your own.
