 		<p>Virtual Sky uses the <a href="http://diveintohtml5.org/canvas.html#divingin">&lt;canvas&gt; element</a> - part of the <a href="http://whatwg.org/html5">HTML5 proposal</a> - so should work in most modern browsers such as Firefox (there are issues in Firefox 3.0 on Ubuntu), Opera, Chrome and Safari. It should also work in Internet Explorer 7.0 and 8.0 through the use of the <a href="http://code.google.com/p/explorercanvas/">excanvas.js</a> library.
