3D-Desktop is an OpenGL program for switching virtual desktops in a seamless 3-dimensional manner on Linux. The current desktop is mapped into a fullscreen 3D environment where you may choose other screens. Several different visualization modes are available.

The transition from working desktop to fullscreen 3D environment is seamless. In other words when the pager activates you see your current desktop appear to zoom out to a point in space where you can see your other virtual desktops allowing you to select another.

Ok, this is pure eye-candy, but I love it

Very similar to the user-switching animation in OS X, but much more useful if you're on a single user machine, since this is a workspace/virtual desktop switcher.
You'll need to have DRI working in X before you can use it. Make sure you read the README to understand how to set it up. The great thing about this is, since it's OpenGL rendered, the animation is very fast and fluid, so it doesn't affect productivity in any way, and it just looks awesome. Give it a try.

This is the home of the graphical boot process for the linux kernel although it is not yet a part of the official kernel. It is, however included in several major distributions. If your favorite linux doesn't include this patch in their kernel send them an email requesting it to be included!

Features:
* Nice graphics (JPEG)
* Antialiased text rendering (TrueType)
* Animations (MNG)
* Progress Bar
* Display of boot messages above or below a graphic. ("verbose" and "silent" modes)
* Fully themeable

You installed EVERYTHING?
I actually use the repositories only when I need to get software that's not in the official Slackware tree. For all my base system updates and other important packages, I stick to Slackware-9.1 or Slackware-current from the official mirrors.

But what you say is true. SWareT is still being developed, and it's not as mature as the Gentoo/BSD ports tree yet, but I'm sure it'll get there sooner or later.
