I have recently opened a new shop at Society6, it's a small but growing collection of images available as small prints, canvases etc but more interestingly available as cases and skins for iPhones and iPads. Society6 also offer cushions, tees and bags.

http://society6.com/anng/cases for the cases - they do look quite cool.
