Just launched in Google Labs: Swiffy, an SWF to HTML5 converter. Read about it here: http://t.co/flysVTO
An excerpt from that link
Today we’re making the first version of Swiffy available on Google Labs. You can upload a SWF file, and Swiffy will produce an HTML5 version which will run in modern browsers with a high level of SVG support such as Chrome and Safari. It’s still an early version, so it won’t convert all Flash content, but it already works well on ads and animations. We have some examples of converted SWF files if you want to see it in action.
