Beryl - 3D effects on a Linux desktop

Here is a nice video of aiglx + Beryl which gives some nice 3D effects or "bling" as some like to call it:

The next release of Ubuntu should include Beryl. It will be interesting to see how they integrate it. I don't know whether it will be available for Kubuntu (which I use), but I hope it will :)

The harder part (I think) will be to find some good uses of this cool new technology. 3D effects are nice and having a nice looking desktop is certainly not a bad thing, but it is also important to keep it usable. In what was can we use it to create a more userfriendly desktop?
