Linux gone mad!

Actually offloading rendering to the GPU should free up CPU cycles. Rendering windows should be a piece of cake for any modern GPU.
Not sure what that is.
From project looking glass maybe? I've heard in south america they are generally more accepting of Java related stuff then most of the rest of us, but I don't know. I don't know portuguese, so I can't tell exactly what those screenshots are.
Lots of people are working on 3d accelerated desktops for Linux.
Like Luminocity, see http://www.gnome.org/~seth/blog/xshots
It's a experimental version of Gnome's Metacity which is OpenGL based. Purely proof of concept, something fancy to show off.
The 'wobbly windows' are fairly useless, but realise that's playing a video real-time on a laptop with a crappy intel8x0-based laptop with free DRI drivers. It's not missing frames, being 'wiggled' and moved around quickly and smoothly AND being shrunk and mirrored in the 'workspace switcher'. All at the same time.
Eventually it's going to find it's way into OpenGL accelerated graphics and related things such as Cairo-based Vector graphics, and very nice text handling, (text gliphs are changed into vector graphics, too) 3d effects, fast transparencies (which can actually be usefull beleive it or not) and so on and so forth.
So you'd get faster scrolling of text, better looking text, infinately scaling text. Scaling windows borders, nice animated widgets and buttons, 3d depth of space for manipulating windows. Much sharper graphics. Smooth window movements, smooth transparencies. Better media playback with lower CPU usage.
(oh, and better printing capabilities too. Strange as it seems.)
for example somebody messing around with 'XGL', which is X.org's experiemental OpenGL-rendered X server, they were able to recreate the OS X 'Expose' effect with only a couple hundred lines of code in a hack.
I can't comment on that 'Gnome 3d' stuff. If it's Looking Glass it may be slow because Looking Glass was based on Java's 3d API and I don't know about the speed.
However next generation of OpenGL accelerated desktops should be FASTER, even with all the eye candy then current generation of setups because they are making much more efficient usage of the hardware.
Also by making everything dependant on OpenGL rendering it helps simplify driver development for X Windows by quite a bit. Right now you have to have 2 sets of drivers (sometimes 3 sets if you take into account framebuffers) with Linux and they need to work together correctly all the time. They should be able to reduce this down to one set of drivers for video.
Also the 2d portions of Video cards pretty much remain unchanged since the early Geforce 1 days. Back when side scroller games started loosing popularity to stuff like Quake1 and such. Those parts of the GPU are tiny compared to the vast majority of the GPU core that is designed to handle 3d acceleration.
When they compare Cairo being rendered on the traditional 2d XRender vs the 3d GL-based Glitz they had several hundredfold increase in performance on some benchmarks...
Personally I am looking forward to this 3d desktop stuff.

Ya. I used Bablefish to translate it too, but there isn't any project called 'Desktop 3d' or 'Gnome 3d', or '3d desktop' (aside from a 3ddesktop, which is a eye candy hack for switching virtual desktops).
That's why I was thinking it was Looking glass. Looking Glass would be the most mature setup out their right now, even if it isn't the most practicle and Sun open sourced it.
But then again it doesn't realy look like looking glass. http://www.sun.com/software/looking_glass/
Maybe it's luminocity or something.

Once they go 3d, the next big problem is how are you going to organize the new dimension. The possibility of windows being to skewed or loosing a window are a problem with 2D as it is!
