The room full of dirt

If you ever happen to stroll along Wooster St just below Houston make sure you take the time to check out the bizarre room known as 'The Earth Room". I do not know what is symbolizes or represents. All I know is that the display has been there since the year I was born. That in itself is remarkable.
