Lockscreen wallpaper changer.

[chuk23chuk]

I'm looking for something that will allow me to make my lockscreen rotate wallpapers every 5 min. Or so. Not like portrait to landscape but the picture change. I have an iPod 4 on 4.1. How can I get this done?

there is a theme called metart and it changes every minute you could just change the images it has but they are a little risque
