I am new to explorer and have some experience with AVS.  I have two
questions - the first more important than the second.

I am interested in connecting a running numerical code to an explorer
network for real time updates of a generated lattice.  Thus I need to
be able to "fire" the downstream modules and it has to be running all
the time.  In AVS language: I need to create a co-routine.  How do I
do this in Explorer?  

I recognize that the contributed Axis module will admit only 3D
lattices, but it would seem that modifying it to work with 2D lattices
(the output of my numerical application) would not be difficult.  In
looking at the Axis.c code, I realize that I do not understand how the
lattice-to-geom module figures out the third (z-displacement)
dimension(?).  Anyway, I am looking for ways to annotate false color 2D
regions in Explorer.  I am willing to give up fancy axes - I just want
to lay down a label in the render module.
