In this post, we wanted to explain a bit about how Cube Slam works. <br /> <br /> Cube Slam uses <code><a href="http://www.html5rocks.com/en/tutorials/webrtc/basics/#toc-mediastream">getUserMedia</a></code> to access your webcam and microphone (with your permission, of course), <code><a href="http://www.html5rocks.com/en/tutorials/webrtc/basics/#toc-rtcpeerconnection">RTCPeerConnection</a></code> to stream your video to a friend, and <code><a href="http://www.html5rocks.com/en/tutorials/webrtc/basics/#toc-rtcdatachannel">RTCDataChannel</a></code> to transfer the bits that keep the gameplay in sync. If you and your friend are behind firewalls, <code style="color: black;">RTCPeerConnection</code> uses a <a href="http://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT">TURN</a> relay server (hosted on Google Compute Engine) to make the connection. However, when there are no firewalls in the way, the entire game happens directly peer-to-peer, reducing latency for players and server costs for developers. <br /> <br /> <div class="separator" style="text-align: center;"> <a href="//2.bp.blogspot.com/-IOnVnFPOJFQ/Ubd7X3c8vWI/AAAAAAAAB68/wCT-9lMjiBA/s1600/4_cube_slam_game_over.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="250" src="//2.bp.blogspot.com/-IOnVnFPOJFQ/Ubd7X3c8vWI/AAAAAAAAB68/wCT-9lMjiBA/s400/4_cube_slam_game_over.jpg" width="400"></a></div> <br /> Cube Slam is the first large-scale application to use <code style="color: black;">RTCDataChannel</code>, which provides an API similar to <a href="http://www.html5rocks.com/en/tutorials/websockets/basics/">WebSocket</a>, but sends the data over the <code style="color: black;">RTCPeerConnection</code> peer-to-peer link. <code style="color: black;">RTCDataChannel</code> sends data securely, and supports an "unreliable" mode for cases where you want high performance but don't care about every single packet making it across the network.

Each device plays one slice of <a href="//www.youtube.com/watch?v=YT0k99hCY5I">Giorgio Moroder’s symphony of sound</a>—requiring five devices at once to hear his full composition. A constant ping from the server helps synchronize all device speakers allowing them to bump to one solid beat.
