Tom,

Russ has done a nice job.  The entire project developed into designing
and implementing an online mathematical sketchpad for graphing basic
functions.  He is meeting with me next Tuesday to go over
the final version of his graphing program.  Although still primitive in
some respects, it is well-designed and I plan on using it in some of my 
classes.  In the future, I hope to find another UG RA who is a joint 
Math/CS major who can carry it further.  When I have his program ready, 
probably late next week, I will let you know how to access it from your 
brouser.
