I've been working on an app for a French sport hospital, designed to browse its msk image library. It's called "MSK view" and it is available for free in iTunes (iPhone and iPad version) and in the Android Market.
Pretty technical stuff in it, not sure everyone will want to install it but hey, there may be some doctors out there!
The hospital is French but the app is both in French and English. Built in Flash Builder with Flex Mobile, Robotlegs and AMFPHP, UI design by Jumo.
Now go show off browsing images of "Scaphotrapezial Synostosis" or "Rectus Femoris intramuscular Haematoma", whatever it may be!
