S5 Presentation 0.1 implements version S5 1.1 (with the exception of iepngfix.htc which looked like a bit too much work as it wasn't needed for my project).  Although S5 appears to be a bit dated, it does work nicely as a simple web based slideshow tool and with the ability to integrate with Umbraco, you should have a slide show up and running in 2 minutes :)
