Sorry folks, looks like iPad wallpapers need to be 1024x1024 to properly handle homescreen rotation. Updated the contest post. (Thanks Damon!)
Here's a shot taken at Pu'uhonua O Honaunau ("City of Refuge") on the island of Hawai'i. I took this many many years ago, on Kodachrome, believe it or not!
No ipad resolution, because the # of icons horizontal vs vertical changes when you rotate screen, but for iphones this is cool. It's like iBooks for your home page.
