I wanna make a wallpaper that changes whenever i do an action (change page, close an app, unlock iTouch, press home button) but i have no idea what to search o.o also i probably could find everything i need through cutting from specialized themes' html codes BUT it's 4:15 am and i haven't slept yet so i'm not in the best condition to concentrate lol. Can someone tell me a theme that's got this function or send me the html coding?

thanks =3
