Google is going to blow up I/O this year with wearables. It's a given. There'll be apps and design sessions and workshops and free Moto 360s for everybody! But before the dev event at the end of the month, they're holding a design contest, and these are the best UIs I saw out of 50 submissions. Then again, I'm not a designer
Unfortunately, they're tasking people like this to judge the designs.
