This is a very cool site which really shows the power of Silverlight 2.
I recommend you have a play with it in IE7
Unfortunately this site doesn’t work so well with Google Chrome (infact most Silverlight applications don’t work to well). The issue seems to be with the rendering of the application.
If you consistently resize your browser, you will find it suddenly works.
It reminds me of those days playing Daley Thompson’s Decathlon on the spectrum, wiggling my Joystick. Now I need to wiggle my mouse to use Silverlight on Google Chrome.
