It is interesting indeed.
One wonders if the researchers of this particular bit of work made it mandatory to go for walks at lunch and think about how their vision chunked/filtered the information it was receiving.
Interesting that they "perturb" the image to get some noise involved. I'll need to read it over again.
Nature is such a good source of inspiration, the "perturb" approach reminded me of [fixational eye movement][1] but maybe that's only a clear link in retrospect.
