Using LiveView to help design for mobile

I've been aware of LiveView (http://www.zambetti.com/projects/liveview/) for a little while but haven't really used it properly on a project until today. I've been designing the mobile state for the new House of Omni site, which is going to be an adaptive site using http://lessframework.com/ I've found LiveView invaluable in quickly gauging what will fit within in the viewport. It's a great app and I advise any one that's designing for mobile to try it out.
