some Vis stuff

[Michael P. Gerlek]

Folks:

Just fyi, I put some notes on the TODO page about making a "What is
OSGeo" slide set for general use, and a "corporate messaging" slide set
based on some IRC conversations yesterday.  I'll start to fill in
details next week.

I also was playing around with some logos of our members -- see
http://www.flaxen.com/all_logos.png.  At some point we should collect
everyone's logos for a complete page like this, it makes for good
presentation fodder.
