Corner corridor artwork 6

This artwork is at a corridor junction in Glasgow's Queen Elizabeth University Hospital.
The text on it reads:-
walk to the end of the path
over mountains and bridges
walk to the end of the path
through every kind of weather
walk to the end of the path
beyond lochs and villages
you want to rest your feet
you want a cup of coffee

but the path continues sideways
the path continues zigzag
the path loops back on itself
until the scenery has gone

but there is no end to the path

walk until the Tea Shack appears
to give you cakes and shelter
