Spaceship Earth is a giant geodesic sphere with over 11,000 isosceles triangles. The 18 story dome is the symbol of Epcot. The outside of its steel shell is covered with 954 panels. Inside is a 15 minute narrated ride tracing the history of communications from prehistoric man through the computer age. It is a fun attraction. Sadly, it did not teach me how to use the apps on my smart phone.
