A good day for conversions and tutorials

Scanning the lastest GIS-centric entries at Planet Geospatial, I was delighted by the posting of some new KML-GML-ArcGIS conversion scripts by Christian Spanring and Matt Perry. Also, today's postings link to tutorials on Local Live Bird's Eye and the Google Maps API. By the way, I'm still working on my wiki for kml--the point being an open spatial database. It's likely to be unimpressive, but should be a fun brainstorming tool.
