Hi Matias! First I want to say I'm a huge fan of everything you do, and you're the reason I started designing for Android and why I want to work at Google someday.

I want to ask a few questions. First, I think everyone here is wondering where you get your awesome shirts.

Second, more relating to design. The material Guidelines are absolutely incredible. They are so comprehensive and include so much, but not everything. When we run into something that isn't included in the guidelines, what would you say the best course of action is? And what is the best way to share what we came up with, with others?

Thanks so much for the AMA!!
