Currently I’m keeping myself busy with my bachelor thesis and web based multi-screen games. If you’ve never heard about it you should check out some of the games below. All of them are running in (modern) browsers and can be played with several devices simultaneously.
As a chrome experiment this game was released by google. It can connect several smartphones or tablets to one big racing track and has a nice soundtrack. Google released a tiny making of video.
A slightly older chrome experiment is Super Sync Sports – a collection of minigames controlled by touch gestures on a connected smartphone. Its visual style is quite unique and reminds be a bit of Rhythm Paradise for the Nintendo DS.
One last google game (I promise!) is World Wide Maze. It turns web pages into 3D mazes that can be solved by controlling a ball with a connected smartphone. For some reasons this game is the most demanding for my poor laptop cpu. The guys from HTML5Rocks published a nice making of tutorial covering WebSockets, physics, WebGL and some more technologies.
