Google has just revealed a new design language for Android, Chrome OS, and the web. The new look which was first previewed in a Google+ app update last month includes splashes of color, refreshed iconography, typography, and a more consistent interface hierarchy. The entire interface is based on what Google calls a "unifying theory of a rationalized space and a system of motion." A video released by Google shows the new design language in action, with radically redesigned versions of Google's apps for Android and the web, including Gmail and Calendar.

A large focus of the redesign is bringing the interface in line with reality. On stage at I/O, Google's Android head Mattias Duarte emphasized that elements, transitions, and animations should appear as if in real life. "Our material is grounded in tactile reality, inspired by our study of paper and ink, yet open to imagination and magic," says Google of the new design language. What that translates to is "material" effects that react to your touch, perhaps with a gentle ripple emanating from a touch point on the phone dialer.

Google's refreshed Android interface will come with the "L" release later this year, but it's available to developers from today.
