OP in that thread doesn't really parse the checkerboard meaning, it's a reference to the supradimensional region where the 'jesters' reside (hence 'order of jesters'), even the masonic mental exercises admit this, their artwork with checkerboard/pillars/etc being a kind of astral/meditation map.

also, ever notice how both western cathedrals and arabic constructions have fractal designs? who taught the 'master masons' about fractals, complex load-channeling geometries ('let all who enter be a geometer'), and use of stereotomy in the design and representation of these structures? the same entities.

he's also wrong about the 911 planes being CGI, although 'planes' might mean smtg else in this context.
