Hi there -
I stumbled upon this little app, which might be useful for everyone who likes glassy windows and doesn't use windowblinds (well, I still do, but anyway)...
It's still beta, but as far as I can see it'll support themes - so you could use it with your visual styles for adding smooth borders and shadows...

It looks to me like a good alternative to VystalVivid (better effects, but as far as I know no themes & shadows)
