I think it's ironic that the moon is in the background since Novel Moonlight is our Linux alternative to Silverlight.Moonlight is an open source implementation of Silverlight, primarily for Linux and other Unix/X11 based operating systems. In September of 2007, Microsoft and Novell announced a technical collaboration that includes access to Microsoft's test suites for Silverlight and the distribution of a Media Pack for Linux users that will contain licensed media codecs for video and audio.
