I'm sure everybody agrees that the wallpapers which came with the N9 are awesome and because of that I was wondering if it would be possible to make the wallpaper switch automatically every time you lock the screen? (i.e. it turns black and when you double tap, the wallpaper is changed)

I don't even know if it can be done, but looking at the other tweaks that appeared already I'm guessing there is is someone here who would be capable of making this a reality. Either with some tweaks or an app.

Hi,

Yup I've already done a simple app-ish for this It switches the wallpaper every X minutes you define. I'll release it as soon as I return to my home/main PC.
