Here's my idea for a wallpaper, it's some animals gathering around an acacia tree.
Animals uniting around an acacia tree at sunset.

It's not the best wallpaper but I gave it a go.
I think it's awesome. It might be even better if only the animals from the Ubuntu releases were included under the tree and a great big heron spreading its wings on top of the tree. Maybe this could be repeated for each LTS release as well ;] - NanleyChery
