Lifehacker reader one800higgins shares a customised iPad home screen with a new clock and a textured background for screens and folders.
This home screen is pretty easy to throw together, so long as you're jailbroken:
This is a custom iPad 3 wood theme I put together. The lock screen is basically a modified Typophone theme. All the wood stuff, including the background, notification centre, folders, and multitasker are all manually added in to a custom Winterboard theme I made. The lockscreen swipe is also manually added in to this theme.
