This one scares me a lot, too. It's horrifyingly much too much well called "earthquake". http://www.ritsumei.ac.jp/~akitaoka/plaidm.jpg Damned and gosh, do these freaking illusions have any biological purpose ??... Should an advanced robotic eye have such illusions ?
[salut Gwendal!] I have been thinking about memory again lately. It seems that if low-cost tricks like these can have such a strong effect on our perception of reality through our visual sense, then it would not be surprising if similarly mundane skewing factors affected our memory in devastating ways. I feel exonerated now. And could the development of robust-yet-faulty storage combined with a generalization of Gwendal's robotic eye idea be an interesting avenue for artificial intelligence research?
