A Game of Consequences

What the artist said (on a small brass plaque next to his exhibit)

There is nothing to
my installation
save tall mirrors,
my arrangement of them.

Stand on the welcome mat,
look into the first, blue, mirror.
You will see yourself,
but in some context
that your brain supplies.
Not standing in a gallery, 
but kissing someone
or killing someone,
or making tea or sniffing coke
or hoovering. Perhaps
you will be sleeping
with somebody unknown to you.

What happened when they opened

A visitor, J Fogg by name,
stood on the welcome mat
and gazed into the mirror
as advised, then slowly,
from an inside pocket
of his smart Italian suit,
he took a glove and, slowly still,
pulled it over his right hand
then smacked his fist against the glass.
A spider's web of cracks spread out across the mirror, and

What was later said by Fogg to explain his act.

                       
                             /             \
                            /               \                                  
The mirror had gone black                    The glass was
bringing on a bout of his depression.        full of smakes
In the total blackness he had seen
a black dog snarling -- seemingly at him

     Most frightening
    were shadows thrown
   by people known to him             The image in the mirror
  with bright light cores           briefly changed, became
 or dew-bright eyes that          an X-Ray photograph of him
shone and followed him.         and showed dark shadows
                              on his lungs and heart,
                            that grew and switched
                          from time to time to dark
                        red, glowing shapes,
                      then back to black
Going dark, the glass
had left him with the
fear that he might sleep --
the terror of The little Death
