I finally got around to looking at the window borders of Jadaero (awesome WBSkin), so I messed around in Paint.NET and created something that looks so much like it that I hope I don't get sued or anything
When I was creating it I used the XP Bliss wallpaper and blurred the area under the window so that it looked like aero.
I'm hoping to make it into a Plus! Skin (minus transparency ), as well, and if you want to help, PM me either on here or msghelp.

EDIT: It looks better on DesktopX than in your browser
The funny thing is, system requirements aside, Aero is just about the only good thing about Vista.
