Nice demonstration and works in IE9, to make it work better in IE7 use this:
<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7"> Needed for .exe programs using IE7, but have IE8 or IE9 installed on windows. Or you can add this for those who have chrome framework installed.
<meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">
Excellent work! Thank you for your contribution to open source.
