Here's a video of the Sense UI stripped out of the Android-based HTC Hero and slapped into the HTC Vogue, the stalwart Windows Mobile device.
Yeah, it's running on Android within Linux on top of Windows Mobile, so it's not you're really running Sense on top of Windows Mobile, like TouchFLO 3D does now. But it is pretty darn cool, and it works pretty well. (What you see here, apparently, is an early build, and things have gotten snappier.) It also has the hooks for basic phone devices. And as Rory mentions in the video, it's more proof-of-concept than actually everyday workhorse.
Keep an eye on the project homepage if this is your cup of tea.
