If you do GIS analysis with ArcGIS you might be interested in a couple of open source extensions that add toolbox tools to ArcGIS. Karsten Vennemann is an expert on open source GIS solutions. He recently gave a presentation to the King County GIS Center User Group and posted his slides for everyone to benefit from. This is a great way to get a good overview of what these powerful extensions can do.
