Ferry app theme chooser

Playing around with some ideas for setting different themes in the Ferry App. The homescreen would use one of the illustrations I designed a while back, and you could swipe left and right to choose different versions.

Once the theme is set, the illustration's colors would dictate the color of the rest of the app's UI (internal pages, etc).

Also considering an option that lets you have the theme change dynamically based on the time of day.
