Gourds, gourds, everywhere.  Part of agreement with the display coordinator was to bring
raw gourds to set around on the shelf tops.  Here's a couple pics. 
I put a large maranka gourd at the one of the entrances and noticed that a few people, 
both young and old HAD to touch the ripples on its convoluted surface.  Gourds and 
touching is a  natural pairing.
