title: Prezi-like web interface. Flash or HTML5?
body: <p>I would like to write a web interface that resembles Prezi.com in its user experience. What would be the best technology for that purpose? </p>
  
  <p>Project requirements:</p>
  
  <ol>
  <li>Fast implementation (it is a demo) - I'd appreciate a rough estimate</li>
  <li>Large amounts of data - dynamic content loading/unloading is required.</li>
  </ol>
  
  <p>My natural candidates are Flash and HTML5.</p>
  
  <p>Prezi.com is an alternative platform for presentations that uses single canvas zoom/pan/rotate controls instead of classic slide-by-slide interface. An example is available <a href="http://prezi.com/jipjiqvj6dsc/about-perspective/" rel="nofollow">here</a>.</p>
  
  <p><strong>Edit</strong></p>
  
  <p>The visual part of my website needs to display multiple widgets (images, videos, text) on canvas and allow the user to navigate by zooming and panning. Each widget would have its own  native zoom. The number of widgets would be enormous, however, simultaneously only a small number of widgets are visible.</p>
