Colorscape is one of my fav projects.
The app helps users print photos from their gallery, from camera or from any of their social networks. The app was designed to be simple to use and also very intuitive at the same time. There were a lot of controls and options to be provided to the user, but the design was to made made simple enough so that the user was not bogged down by them too!
Here are some of the screens of the app. The app would soon be live on App Store.
