stack and tile is cool

So I was looking through the developer emails and I noticed some hubbub about stack and tile. It wasn't something I was familiar with so I went ahead and searched for it. The video demonstration is below if you are lazy but curious.

I must say, this is a very cool way to handle windows. I can now see why there was such buzzing interest in the developer mailing list on the subject. All I am saying is, if this stack and tile is something you have not heard of before, you should check it out, it's a bit exciting.
