At its annual IO developer keynote, Google has released a new design language for Android, Chrome OS, and the web. Google's calling it Material Design. The new look - which was first previewed in a Google+ app update last month - includes splashes of color, refreshed iconography, and a more consistent interface hierarchy. The entire interface is based on what Google calls a quote, "unifying theory of a rationalized space and a system of motion." Yeah, it's a mouthful.
