I've put together a quick demo of a menu idea for a mobile website or app. It only took me 20 minutes to build the entire prototype. Feel free to import and dissect.
This is an interactive dial pad, created with proto.io.
Development & original idea: https://spaces.proto.io/akisioannou
Graphic design: George Prentzas
Full app prototype for IslandBreak Bahamas travel Guide - Discover & explore the islands of The Bahamas with a smart mobile travel guide.
