title: Framework similar to Adobe Flex with HTML5
body: <p>is there a framework that is similar to Adobe Flex written in HTML5?</p>
  
  <p>My app currently support having multiple objects on the screen where user can drag / drop / resize and rotate them in scrapbook fashion. There are few animations as well. Flex makes it easy to build such apps. I was wondering if there is a good framework I can use to ease up such task maybe with HTML5 so it can be used on mobile devices.</p>
