Compiz Fusion now officially has a logo, which you can see here. They've also added some new animations. One folds the window up into a paper airplane and lets it fly off-screen or down into wherever your windows minimize. Another folds up the window until it disappears. Finally, there's one called "Skewer" which chops up the window into little bits and swirls them around. You can see what that looks like with this video:
The existence of an official logo means that it is now possible for an official Compiz Fusion release to happen (more details here). I can't wait to see the release. I haven't tried CF yet. I think it still needs to be compiled, unless you use Trevino's repositories, but I've heard of issues with those repositories as far as dependencies and messing with your current Compiz install. You might end up with an upgraded version of something that was working fine and breaks, so I don't really recommend using them unless you know what you're doing and can revert to old versions if you need to.
Some time in the next couple weeks, I'll be installing Gutsy on a spare hard drive and Compiz Fusion on that, and I'll let you all know how it is and what new stuff I like. Enlightenment 17 will also be featured soon (as soon as I finish building all the extra stuff I want on Debian Etch...no repositories for that yet, so I may just learn how to make deb...maybe), so stay tuned.
