I had the great opportunity to help Crayon Digital get enabled on Silverlight for one of the projects they had to deliver for the SingTel Singapore Grand Prix and I have to say, they’ve come up with some pretty sleek stuff and I’m sure you GUYS will agree 
Check out the Heart Race Test which the team has very impressively built in less than a month, including time taken to build the concept, assets as well as honing Silverlight development skills!
Loads of videos on the Grid Girls but my favorite is how they used Deep Zoom. Check the site out!
hmm…well to be honest the game strikes me as sexist. he he
but anyway it’s still a cool piece of work in Silverlight 
hopefully if the olympics didn’t get the guys to install Silverlight this one probably will
