(Updated: Corrected link to the sample presentation.)
Anil Dash from Six Apart posted instructions for implementing Eric Meyer’s S5 slideshow system with MovableType templates. This is a great example of both the simplicity of the S5 system and the power of a template-driven website.
In a couple of minutes, I implemented the technique on Cantoni.org to see how well it works (see Cantoni.org Slideshow for the result). The longer posts and images overflow the page, but it’s a quick example that shows what is possible.
