I'm playing with something wild - see:  http://www.server-sky.com 

30 gram, 40cm wide, 100 micron thick silicon Earth-orbit satellites. 
Of course, most of the work is software simulation right now, and
there might be people on this list working with open source tools
that I can co-opt.  I'm looking for:

1) Orbital simulation (numerical engines, not GUI eye candy)
2) radiation models of the magnetosphere
3) hypervelocity impact simulation
4) phased-array simulation
5) Animation tools compatable with openoffice

I am doing a lot of work right now with gnuplot, and libgd.

Some of the large array calculations will be done on an Nvidia
GPU programmed with CUDA, so I would like to hear from people
working with those.

And of course, I am always looking for volunteers ...
