Current TechnologyScience on a Sphere – SOS

Exhibit display developed by NOAA for use in Museums/Planetariums across the globe

• Currently cycles through pre-made animations

Needed: An interactive learning experience for exhibit visitors

GUI Emulator

Neal Robbins Interpreter 22

Demonstration

GUI spits out code based on User's input

Interpreter runs the code and generates a folder containing the animation images

User Interacts with GUIEmulation software shows animation
