I came across these today, wondering if anyone has tried them out, i'd like to see a video of them in action before diving in!
DreamTheme.mobi
It's an application that runs and functions as an animated home screen, and can still access the traditional homescreen. Also included with the application is a theme to match your selected style. They have custom icons including aftermarket application icons to match! There's 7 different themes, and they're going for $9.99.
I know I sound like I'm giving a sales pitch but it sounds great to me, I'll definitely be getting it once i can see a video of the interface and how it runs!
