Adobe has revealed Wallaby, an experimental tool that enables you to convert Flash content into HTML5, albeit with some limitations. You can check it out over here.
"Wallaby" is the codename for an experimental technology that converts the artwork and animation contained in Adobe® Flash® Professional (FLA) files into HTML. This allows you to reuse and extend the reach of your content to devices that do not support the Flash runtimes. Once these files are converted to HTML, you can edit them with an HTML editing tool, such as Adobe Dreamweaver®, or by hand if desired. You can view the output in one of the supported browsers or on an iOS device.
Please note that not all Flash Professional features are supported in the HTML5 format. The Wallaby Release Notes describe what features are supported, what differences we have already discovered between the various browsers, what device variations have been found, and any currently known issues.
