You can see an example here:
I explored html5 slideshows quite a bit, and I had two main issues that got me interested in writing my own:
Every html5 slideshow I saw had online dependencies. I understand that the web is everywhere, but I still didn’t want to rule out situations where internet access is not readily available. Simply saving the slideshow locally with a browser was a viable option, but I preferred to also clutter my file system as little as possible.
The markup wasn’t always straightforward. I was recommended both the google html slideshow and rubyforge’s slideshow, but I didn’t like the idea of having to learn a different proprietary markup, especially when html is about as simple as markup gets.
The slideshows included little fixes to make up for css3 technologies that weren’t supported. I didn’t like this. I was looking for something that doesn’t sacrifice simplicity to try to make the code work for less standard-compliant or outdated browsers. My system works for the newest browsers, and I don’t imagine that changing.
I would love to see some feedback, and I am willing to add more functionality as requests come in. So please, give slimy a shot! I have a feeling you’ll rarely use Powerpoint or any other slideshow application again.
