I’m a firm believer that the best and most successful self-initialed projects grow out of a personal or shared passion. This is precisely the case with Proof, a new project from the creative minds at Zeus Jones. Since many of the team members are Scotch whisky connoisseurs, it was a natural progression to turn that appreciation into some sort of marketable product. That idea developed into Proof, an iPad app that turns whisky tasting into a group game. To promote the new app, they also created a series of hand-printed tasting kids, which include one whisky from each region of Scotland. If you also consider yourself a whisky aficionado, you can install and play Proof on your own iPad for free right here, and learn more about the creation process and design detail in the Zeus Jones portfolio.
