It appears that I got a bunch of new wall papers with today's update of Ubuntu 11.10 Oneiric Ocelot in the Beta. I like the train station wallpaper the best, as it seems to blend in with the Unity panel and Ambiance theme quite well.
Here is a screen shot of the new Ubuntu 11.10 Oneiric Ocelot wallpaper with the Dybbоlsbro Station featured.
There looks to be about 15 new wall papers to choose from in Ubuntu 11.10 Oneiric Ocelot. Now that they are getting closer to release, I have been seeing very few crashes of desktop applications on my Dell Precision 360 workstation.
