ABSTRACT = {If rooms in an office building are allowed to be any rectangular solid, how
many colors does it take to paint any configuration of rooms
so that no two rooms sharing a wall or ceiling/floor get the
same color? In this work, we provide a new construction which
shows this number can be arbitrarily large.},
