Coca Cola
Character illustration created for Coca-Cola's ill fated "Make it Happy" campaign introduced during Super Bowl XLIX.
Characters designs were to be transformed into ASCII art, using negative tweets as source material, thus transforming negativity into something cute and playful.
Which was the theory until someone created a bot that auto tweeted passages of Mein Kampf to Coke, and that was that.
Regardless, it was a fun to create a bunch of fun characters using only basic geometric shapes. And hot dogs.
