--> Compiz 3D models "How To" <--
To install 3D models in your compiz cube
(just the models not the plugin itself)
[9.04 jaunty]
-#1 Go here and download the 3d models you want, (I am running Deepspace, earth and moon, EvE and Rancor, But as you may have guessed I have them all!)
(Deep space is an immediate gratification )

Unpack the tar.gz and open the folder, look for the .obj file that is the working file, you also want to open the file to see if there is another ta.gz in it that has another model, Create a new folder in your home folder, Name it 3d models, Put all your unpacked model folders in your 3D model folder in your home folder, Do what you want with the tar.gz (I make a folder for storage and put it away for back-up)
-#2 Open CCSM > (shut down Atlantis and gears for now If you have them running)
open cube 3D models Click "new" a new window will open click the folder icon and navigate to your 3D models folder, Find the model you want, Open that folder, Click on the .obj file, Your model is now loaded.
-#3 click the "scale factor" once, This is preset to 0.0100, Sometimes the model is to small at that setting and you cant see it, BE CAREFUL with this setting only one or two clicks is good at this point until you see the effect it will have, To many and your model will over whelm your cube, They get real big real fast! With all the settings at there default positions, Transform, Into your cube, Model should appear in the bottom right of your cube,(at this point I recommend you make your desktop transparent so you don't have to keep deforming your desktop to see the adjustment you are making, And ether "roll up" the main CCSM or send it to another desktop, SLOWLY make adjustments until you achieve the desired position, Slowly bring up the rotation speed, I find at this point animation will spin and turn with the "model type" set to still (I haven't had a lot of time to experiment yet),Go ahead and make slow adjustments and experiment with the settings, Not all the setting will be the same for other models, Some not even close, So you will have to make adjustments accordingly, Once you have the hang of it, Install your next model as above, You can install as many as your systems video card will handle! You may also activate Atlantis and or gears(at this point you will probably say good by to gears!) THATS IT! Now doesn't that beat the hell out of everything else you've read!!!, ... Take that Teckie"s!!
.....Your welcome! My pleasure!
NOTE : Some models have very large files some at over 150mb due multiple models in the file. Some models are very system heavy, and some light as a feather, there are other models on the net, Some work some dont. Also,At this point the only file type that I have found will operate is .obj, Other 3D model files can be imported to blender then exported as a .obj file.
ALSO : If the model file has a lot of .obj files, that is an animation, I have read to, load the first .obj file and the plugin will take care of the rest!
( I will update this post as information becomes available)
(god I love the smell of a brand new how to)
Have fun! Johnnyg
...... have you installed any other models yet? I'm curious to see someone else's output, and how it went! 
.I didn't do everything you did,and it didn't work.Ill follow your instructions in a min,and see how it goes.I did find something on a Ubuntu French site called cubethemer.Don't know what its supposed to do exactly(I don't speak French).Anywho I run the app,and it errors out.As far as I can tell its telling me I don't have the model plugin....but I do according to compiz.
Its kinda tricky to get it set up just right tho.
