Busy? I don't see how a subtle repetitive texture like that is busy.
Everything is clear and works with the desktop swiping parallax well, I hate busy wallpapers where you can't find things so was surprised by this response.
Anyway I am not sure if the wallpaper alone is what the topic is focusing on here. Themes may come with wallpaper but there is more to themes than the wallpaper.

I was also pointing out that the digital nature theme we already have from Fremantle could also be an option. I don't see why we need to reinvent the wheel if it's such a personal thing. Ideally themes from extras could be available?
