My computer does all of this stuff, and it does it with dual monitors. Does yours?

Seriously, this is XGL running on top of Xwindows for Linux. it is just a way of getting all the eye candy you ever dreamed of for Mac OS X and Windows Vista, and then some more stuff that you didn’t even know you wanted. The best part is that it is an architecture that supports plugins, so if you don’t like one of those things, you disable the plugin for it, or if you want it to do something it doesn’t someone might already be writing that into it as a plugin.
Once you get used to the flipping cube thing (or just virtual desktops in general) it is really hard to go back.
I’m happy the new OS X Leopard is going to have virtual desktops in it.
Seriously, I never knew eye-candy could improve my productivity until I started using XGL with some of these plugins.
