The project contains numerous examples completed using variables and conditional logic.

This is a UX design prototype for Pandora's Android app (from October 2014), adding a "Driving Mode" and lateral navigation between stations from the Now Playing screen. I took a challenge to redesign Pandora's Android app or add features at my discretion. Focusing on the Now Playing screen where users probably spend most of their time, I identified two areas in which I wanted to improve its UX: station identification and navigation, and its user experience while on the go. A 7 minute 25 second presentation of this demo with commentary is available on YouTube: http://youtu.be/LyH6Gl580OY A full write-up of an earlier, pre-Proto.io iteration of the design (along with a downloadable pdf) is available at http://edwinli.com/ux/portfolio/pandora-driving-mode/.
