2D Animation for Web Benchmark

Came across this great site for comparing recent 2D graphic/animation technologies for the internet today. The site has nice 'colliding balls' example done with different technologies (DHTML, Java Swing, FLEX, WPF...).

I love working with Silverlight and javascript. I was looking for performace comparision between Silveright+Javascript and Sliverlight+CLR. Though the Silverlight + javascript , example is lot slower (around 50 fps on my machine) than the CLR one, I think it has lot potential. However when performance is required, nothing beats Sliverlight+CLR, it seems !
