It looks like an app. That's on purpose. Drawing inspiration from smartphones, Gavin Rea's TouchCal is a concept design that brings the scientific calculator out of the '90s and into the future. Physical buttons at the bottom retain the tactile experience preferred by frequent users, but cover only basic functions, while more advanced options are presented on the color touchscreen on a context-specific basis. As a result, it provides the best of old and new, all hidden behind a protective cover that doubles as a kickstand.
