Test Silverlight speed or Test CPU speed with Silverlight

While we were developing SilverBench (online multicore CPU benchmarking with Silverlight), I found one interesting benchmark project.

It is called Balls / Bubblemark animation test. You can test and directly compare speed / performance for the following programming languages: JavaScript, Silverlight (C#), Flash (ActionScript) and Java. Source code is provided. Project is maintained from 2007 and last time updated in mid 2009.
