<p>If you can the example screens above, Ebiten is working on your browser! Each example above works as an independent html in an iframe. If you want to execute the examples apart from this site, execute this:</p>
<pre><code>:; go run $GOPATH/src/github.com/hajimehoshi/ebiten/example/server/main.go</code></pre>
<p>Then, open <code>localhost:8000</code> on your browser.</p>
<p><code>localhost:8000/?EXAMPLE_NAME</code> shows other examples (e.g. <code>localhost:8000/?rotate</code>).</p>
<p>Of cource, you can execute gopherjs yourself. Please see <a href="http://gopherjs.org/">GopherJS site</a> for more detail.</p>
