If nothing else try and relate the object to an emotion you can understand. First think of your anticipation and enjoyment of a jelly donut! The void of wood at the top is your feeling of emptiness of not having the jelly donut. The thickness of the wood is your enjoyment of said donut. When you get to the center you do what every does but are not willing to admit. You go a bit wild and try and slurp up some extra jelly before biting deeper into it.

The holes in the wood are drops of jelly spilling out of the donut and onto the floor. Grrrrr now you have to clean up the mess. The stains on the wood is the powdered sugar getting all over your fingers, and you washing your hands not wanting sticky fingers while eating it.

How fun would it is if you went into an art exhibit and explain a piece of artwork like that. Why you would probably be looked at like a crazy person!

Oddly enough I feel the deepest thing there for me at least is just the pile of tarps laying in the middle of the room.
