title: Best technology option for implementing RIA with Rails as the backend?
body: <p>I'm working on a application that requires a feature-rich media view, including images, videos, and smooth sequencing based on capture time. The backend is currently written in Rails.</p>
  
  <p>What's currently the best, most mature option for implementing RIAs with Rails on the backend? I've looked at Flex, Laszlo, and ExtJS. ExtJS is interesting to me because I'm really not a fan of pure Flash UIs, but it seems highly targeted towards business apps, not entertainment applications like this.</p>
  
  <p>Any suggestions or insights from others doing similar efforts will be very much appreciated.</p>
  
  <p>Thanks!</p>
