[Image-SIG] that's enough

[Jack Uretsky]

Hi-
 	Thanks very much.  My "more detailed explanation" seems to have 
confused the issue. Here is a more detailed, more detailed explaation:
 	The principal program calculates the state of a 3-"spin" assembly, 
each spin can either be up or down - there are, accordingly, 8 possible 
states.  The spins "flip" singly and randomly, as described in the Cornell 
ArXiV 0912.4068 (gen phys).  I have prepared .jpg's showing the 8 possible 
configurations.  When the principal program calculates a new 
configuration, I would like to show the relevant .jpg.
 	There are undoubtedly a plethora of ways to illustrate the process 
I am discussing.  Did I choose one that is too difficult for a simple 
python progam?
 			Regards,
 				Jack
