I came across this Wordpress plugin while building the website for my new web serial. What it does is detect if a user is using a mobile device such as an ipod, android, or blackberry and then displays your website in a clean format and display for that device. I tried it on my site on an ipod touch and it made my site look like an app complete with touchscreen support.
Really easy to implement.

If you have a mobile device you can see it in action on my site here:
