Fig. 3 of this paper looks a lot like the "C-runs" artifact on Affy chips.
Other Naef & Magnasco and Magnasco lab papers are also quite interesting in
relation to Affy analysis -- see http://asterion.rockefeller.edu/felix/CV .

RNA binding to high-density oligonucleotide arrays has shown tantalizing
differences with solution experiments. We analyze here its sequence specificity,
fitting binding affinities to sequence composition in large datasets. Our
results suggest that the fluorescent labels interfere with binding.....
