Dear Dom,
I totally agree Steve Job's opinion about Flash. Some mindmap are based on Flash and I don't buy the idea. We are on SVG technology, which is main drawing component of HTML5. So, most of web browser run OKmindmap. The site is http://okmindmap.com and my presentation video made with the okmindmap. The map address is http://okmindmap.com/map/ZDlhODQ3ODktMjU0Zi00NTlkLThjMDEtOTgxMDgwYWVjYTI4
You can run it faster on Google Chrome!
