Bulging Checkerboard

Andy0306uk built this great bulging checkerboard, an illusion first created by Akiyoshi Kitaoka. The explanation lies in how our mind tries to make straight lines out of the patterns of small dots that alternate back and forth around the lines that are actually straight. BTW, Arthur Gugick and Tom Remy have also built versions of this illusion.
