Microsoft won't allow UI mods on Windows Phone 7. That hasn't stopped HTC from bringing their trademarked Sense UI feel to WP7 though - instead of replacing the homescreen outright, they added apps that replicate a lot of current Sense UI's features.

This videos could potentially be a fake - but a lot of work went into it, too much for an Internet prank. If they are real though, Sense enabled Windows Phone 7 from HTC will raise eye-candy to levels seen only in prototypes.

Here's the first video - everything happens with smooth 3D animations. Everything. The notes application is wonderfully ornate and the weather app adds fly through clouds animation to the already elaborate setup.

And another video - this time the software is running on an actual device. It shows the HTC Hub, which is a lot closer to the current Windows Mobile Sense UI look, weather clock and all.

Some of the apps look like cute toys - like the "Loves me, loves me not" game and that app with the flashlight icon (they don't show it, but what could it be other than a flashlight app).

As cool as those animations are (and they are very cool), on a day to day basis they'll probably become an irritating delay more than a feature. Most likely they can be turned off, when you get bored with them. Oh, and was that copy and paste support we saw? Windows Phone 7 doesn't have one usually.
