This thing looks awesome. We don't have a ton of details, although Engadget has a nice writeup, so just watching the really cool demo video.
This is the kind of thing I love that Google does.
I tried to write this yesterday, but it was difficult to feel happy with another mass shooting in the news. So this #happy post goes out to all those in Vegas, and those with friends and families who were injured. Also still thinking about those in Puerto Rico, Texas, and Florida.
