An example presentation apparatus having a cabinet-like base and a surface
coupled to the cabinet-like base and configured to hold an object. The
cabinet-like base and the surface are configured to cooperate
functionally with a function of the object. A portion of an air
processing apparatus is disposed within the cabinet-like base and
configured to move ambient air through the cabinet-like base to generate
processed air. An exhaust structure is operatively coupled to the
cabinet-like base and configured to enable the processed air to exit the
presentation apparatus via a flow path that is spatially associated with
a substantially predetermined position of the object.
