This looks to be damn cool. Looking at the docs[1][2] it's now possible to create a Spotify remote control (e.g. control PC from a phone) using the native client. Thinking about it, it's probably also possible to sync two Spotify players on different computers, although they would have to be using different accounts...
It would have been nice if the manifest.json used the Chrome extensions format rather than creating yet another one, but otherwise the developers should be congratulated on using plenty of HTML5 stuff, and what also looks like CommonJS modules.
It would be really good to get some Selenium tests written up for them as well so that we know they all, and all future ones, behave the same. I might do this if I get a bit of spare time.
After seeing the demo I thought this was being done in canvas, but no, it's actually using css transforms applied to DOM elements. SVG is far more suited to this task.
There have been several attempts at solving this, including one by Microsoft[1] which involves putting a camera on either side of the screen and synthesizing a new image that allows eye contact.

I'm looking forward to seeing what comes of this!
