Got the steam punk Gelaskins case yesterday, they can be a fiddle to fit but incredibly thin and adds grippines to the iPad.

Not all of the iPad 2 styles are labeled as compatible with the new iPad on amazon. From the offial site though ipad2 cases are all compatible.

Some other nice designs are: Starry night by Vincent Van Gogh, The Loneliness of Autum by Leonid Afremov and Blue Willow by Colin Thompson.
