Ubuntu 13.04 and Compiz Desktop Cube

The best installation guide I've seen for configuring the Compiz Desktop Cube is http://www.youtube.com/watch?v=hwgeR_ZXhGc which is for 12.10, but with a couple of warnings below works fine in 13.04.

1. Close everything else before following the instructions - restarting a real possibility.
2. Enable Rotate Cube, not Desktop Cube.  Enabling Rotate Cube will ask you if you'd also like Desktop Cube.  Enabling Desktop Cube first locked up my window system.
3. Don't click on the Workspace Switcher until after everything else has settled down! I haven't tried this multiple times to figure out exactly what happens, but it hasn't been good.

The summary (if you've already watched the video) with my personal settings:

1. Close all windows / applications
2. sudo apt-get install compizconfig-settings-manager compiz-plugins compiz-plugins-extra
3. Start the CompizConfig Settings Manager
4. Under General -> General Options -> Desktop Size:
• Horizontal Virtual Size: 4
• Vertical Virtual Size: 1
• Number of Desktops: 4
5. Desktop -> Select Rotate Cube, allow Desktop Cube to be enabled
6. Desktop -> Desktop Cube -> Appearance: Set the Top & Bottom to something compatible with your background
7. Desktop -> Desktop Cube -> Transparent Cube:
• Set both Opacity fields to 50%
• Clear Transparency Only on Mouse Rotate
8. Desktop -> Rotate Cube -> Bindings -> Rotate Cube -> Initiate: Button1
9. Desktop -> Rotate Cube -> General -> Zoom: 0.3

Edit 26 Mar 2013: I've toned down the comments about the Workspace Switcher.  After a reboot it now behaves as before installing Compiz Settings Manager.
