These are mockups that I designed for Sky-Skan's software. They represent three use cases for planetarium operators: playing a saved presentation, performing a live presentation, and editing a new presentation.
The bar at the top is a user-defined arrangement of widgets called the bridge, which gives users easy access to their favorite functions by allowing them to drag interface elements from elsewhere on the screen. A fourth mockup was featured in an ad on pages 36 and 37 of Planetarian Magazine's March 2015 issue.
