I have been receiving messages now and then from the group. Although I 
don't always respond, I do enjoy reading what everyone is up to!
I recently received email from someone who is setting up a Science 
Center with hands-on activities in California somewhere.( I can't 
remember the  exact location right now, but the plans include an IMAX 
theatre.) He was looking for voronoi activities to use with light 
beams.  He found our site through a search engine.  I find this to be 
pretty amazing stuff!
Hope to hear from others, too!
