Blacklight is a Codeplex project created by my colleague Martin Grayson. It is an open source repository for Silverlight and WPF controls.

Version 3.0 has recently been launched bringing an impressive collection of controls and styles. A showcase demonstrates the controls at http://mightymeaty.members.winisp.net/blacklight.silverlight/.

I'm hoping to be developing a few controls of my own for Blacklight soon so keep a look out!
