GRASS vs. ArcGIS: Thiessen Polygons

This is the first of a few showdowns, or throwdowns if you prefer, comparing open source GIS' spatial analysis tools to ArcGIS.  This week: Thiessen polygons. You will need an ArcGIS Advanced Desktop (formerly ArcInfo) license to create these, or some patience with open source software.

See below for a comparison.  Unfortunately, QGIS produced some different/strange results.  I'm not sure why this is but I am investigating.  Haven't tried with pysal yet.  Anyway, see below.  Fyi.
