I have a Joomla website that I am working on and I created a simple animated logo using your Sencha Demo. I really love the software by the way. The problem I am having is that everything works perfectly the way I want it to in Google Chrome, however if you go to safari there is a white background behind the animation. I am using and Iframe for the animation placement. That is the only way I could think of to incorporate it into a joomla website.
