…and Mark's present: he has 15,000+ books and his ceilings collapsed quite some time ago.
This is actually an art installation for VIA advertising agency which has moved into a former public library in Portland (presumably Oregon). This is, of course, the kind of thing that these disgusting people might think 'ironic'. I prefer to assume that the artist is using the books as a kind of threat: that they represent erudition and conscience, eternally promising to break through the psychic defences ad execs raise against the possibility that morality might invade their daily lives. The artwork is in the basement - unlikely to be seen too often I suppose, but symbolically representing the unconscious which always threatens to irrupt into the consciousness.
It's pleasing to imagine that the shades of the building's former upright purpose might crowd round its new and unwelcome inhabitants.
