Whise, of screenlets fame, posted a tip for enabling 3-D mode in Docky.
You must have Docky (not Gnome-Do Docky) installed. Once set head over to the Configuration Editor.

  • ALT+F2
  • type gconf-editor
  • Navigate to /apps/docky-2/Docky/Interface/DockPreferences/Dock (whichever dock you want to enabled it on)
  • Check the box next to ‘ThreeDimensional’
  • Boom! 3-D Docky
 
BZR Users

Docky BZR users can enable 3-D from the Docky Settings menu.

  • Click on the Docky Icon on the dock
  • Tick ‘3D Background’.
  • Errr. That’s it!
