Using spatial analysis to find Waldo

I like the way that this guy thought systematically about finding Waldo, a classic spatial skill of disembedding or finding hidden figures!  Since he suggests that there is a specific section of the whole page where Waldo is more likely to be found than elsewhere, we shall test this hypothesis in our advanced GIS class next semester, with a few spatial statistical tests. Just to confirm that his horizontal rectangular swatch does indeed capture the most frequent placements of Waldo.

Thanks for publishing such important stories, Slate.
