Expose feature like OS X

[lio04]

Do you know any feature, which is similar like this ? I know, that this feature is also plugin in Compiz, but there's no point to install Compiz, for one feature. I have Debian lenny, the best solution will be *.deb package, but it's not required.

I found only Skippy, but last package is for Sarge and tar.bz2, it's non-functional.

Thanks for ideas :)

Compiz is the only thing I can think of.
