Well, it's a tough row to hoe, so to speak. It looks like there are 
tools on VTerrain that can model forests. There are some garden design 
applications that can model a garden layout in 3d (often using cutout 
2d images of plants, shaded, scaled, and placed based on their 3d 
positions) so not all 3d.
Anyway, it might be possible, but it's a major venture, in a rather 
different domain from a plant/design element database system. They 
definitely are keeping up with the technologies, but me thinks we're a 
few years off before systems like that are full fledged.

Also to note, Touchgraph isn't really 3d, but mimics some physics to 
make connections springy, which happens to be a reasonably efficient 
way to arrange connected nodes of a graph. I really like the tactile 
feel of these systems. Now I'm just trying to grok how we expand upon 
single property linkages to visualize more complex connections and 
networks.

It does seem like it may be possible to take a Lat/Long point, and 
derive from it slope, aspect, average precip., temperature, 
photosynthesis, etc and perhaps pare down the suggested plants to match 
within their ranges, soil needs, etc. You'd probably want to use a 
ranking system on this, so the results were somewhat fuzzy. Don't want 
to completely exclude a potential plant based on roughly recorded 
range, etc. If we could connect to the USDA Plants DB, we could check a 
plant was ruled invasive in a state or county, so designers were aware 
of what to be cautious of. Found a few databases of GIS linked 
vegetation cover info today. Seems like there definitely are 
interesting projects out there, but how easy it is to meld and play 
with the data is another question.

On another note, the OneVillage Foundation seems quite interesting. 
Creating eco-villages in Africa and elsewhere, bridging the digital 
divide, selling fairtrade products to boost the local economies, and I 
see mention of permaculture in one of the documents.

Something that I thought of when I was developing OpenPermaculture was 
that it would be really cool to link up with actual sites in 
"developing" countries, have a digital camera over there. Get photos of 
the site, have people back here study and research, and generally help 
in the design process via the net. It seems like this would be an 
interesting thing to play with. Not necessarily as part of our project, 
lets keep the scope reasonable :-) ...you'd develop an archive of the 
transformation of the site, get documented case studies, get research 
done, etc. There's actually a website doing something like this called 
Nabuur, see nabuur.com.

Also found http://www.thinkcycle.org/ out of MIT. Interesting projects 
and ideas if you feel like surfing for a bit. Might be interesting to 
post this project and goals, see what advice we get from there.

OK, tangental discussions.

Cheers,
