I made a little iPhone-friendly web app for browsing artists and images in Freebase (using Acre, which is getting to be very useful).
It's clonable, so please go ahead and make your own fork. If you can get swipe-to-view-the-next-image working, that would be great.
The images are all from Wikipedia originally, I think, and are a bit out-of-date (some larger images have been added to Wikipedia since they were imported to Freebase). It would be nice to add the capability to easily replace any of the images with better ones, if they're available and out of copyright.
