			<content:encoded><![CDATA[<p>In other words, is Y up, or is Z up? It&#8217;s a loaded question. My <a href="https://www.youtube.com/watch?v=W8hmWWoaUyU">little lesson</a> from <a href="http://bit.ly/ericity">the course</a> is here, in case you don&#8217;t know the issue. What&#8217;s more entertaining, and the point of this post, are <a href="https://www.youtube.com/watch?v=0PpgnT-oEms">the answers I got back from the people I asked</a>.</p>
<p>Speaking of cameras, is there nothing that three.js cannot do? Check out <a href="http://learningthreejs.com/blog/2013/03/12/move-a-cube-with-your-head/">this incredible piece of wonderfulness</a> and have a webcam ready. Or go <a href="http://jeromeetienne.github.com/tquery/plugins/headtrackr/examples/index.html">right to the demo</a>, and then <a href="http://jeromeetienne.github.com/tquery/plugins/headtrackr/examples/demo.html">the other demo</a>. It&#8217;s one of those &#8220;of course we should be able to do that&#8221; kinds of things, but to have it just one mouse click away (assuming you&#8217;re set up to run WebGL; if not, go <a href="https://www.udacity.com/wiki/CS291/Enabling_WebGL">here</a>).</p>
