Three of the spreads have been (successfully) solved, leaving a scruffy aura around each object. Three are yet to be solved using the last page of the book with its cheerful display of gravity free objects.

The voids have a particular attraction, not because of their conceptual basis but because of the curious tensions injected into ordinary domestic scenes, as if a superior power had chosen to edit reality as a kind of punishment.

An added excitement lies in an alternative option of the owner colouring in the voids, producing a ghostly effect I reckon.
