    He is not senile. It was a joke. It’s just that Alzheimer made him forget he already used it.

            Wouldn’t checkering itself, even in the abstract, need to reference two discernible colours or shades, and so, wavelengths of light, and so, some extension along a z axis, and position in time? Is it possible even for an abstract checkered pattern to be defined in any less than 3 dimensions + time?
