I don't post much on graphics stuff, but this is pretty cool, IMO:

In response to my XAML By Hand? post awhile back, I became curious about what it would take to export Avalon-friendly XAML from a tool like Adobe® Illustrator®. So, I downloaded the publicly available Illustrator SDK, and I’ve been spending some spare time in the evenings working on a plug-in.

Well, the plug-in is far enough along at this point to be relatively useful, so I’m releasing it to the public as a free download. The current version works with Adobe Illustrator CS and CS2 running on Windows. Note that this plug-in is not endorsed, warranted, or supported by Microsoft. It was created by me after hours, so use it at your own risk.

So if you're an Illustrator geek and want to play with XAML, this should be a useful tool.
