In the process of doing some other things, I have just noticed that those who thought the "Barf Bag" wallpaper that showed up in Ubuntu 10.10 Beta was just a "placeholder" were probably correct. The latest UNE Daily Build has a significantly different wallpaper:
The colors are still the same (and I'm still not crazy about them) but the overall appearance and effect are much nicer. Using what someone else said about the previous wallpaper, this one no longer "looks like I dribbled sauce out of my burrito onto my screen".
For those who are curious, this screenshot is from my Samsung N150 Plus. The new UNE release is looking very good, I actually like it quite a bit better than the original/current version. Considering that it is still two weeks away from the Release Candidate, it seems quite stable. This is shaping up to be a a good release!
