This is an interactive dial pad, created with proto.io. Development & original idea: https://spaces.proto.io/akisioannou Graphic design: George Prentzas

This is a prototype that demonstrates you some of the capabilities of Proto.io. You are welcome to import this project and use these interactions in your prototypes. In this prototype you will see drag animations in all directions.
