Thanks to Dr. Henk Scholten for sharing some great spatial examples in his plenary address to the ESRI Education Users Conference. One that caught my eye was a Dutch ad for coffee. http://strangemaps.wordpress.com/2008/05/26/278-ice-coffee-town-the-netherlands/
You can examine some of his work at EduGIS (www.edugis.nl) and GeoDan (www.gedan.com).
He shared some great perspectives on how GIS affects the development of spatial thinking.
