Watched Temple Grandin TED Talk and Daniel Tammet.
The latter was not really audible.
So watch it again.
Homework: Hexayurts on blog of those who haven't done it yet.
Make sure you explain process and measurements and use pics that show scale and relevant details and views - eye-level, overview, base, inside if need be...
Get the powerpoint
Get google sketch up, do/make a virtual 3D hexayurt's inside and outside or do/make a geodesic dome inside and outside or do both.
Kamini R Rao made a presentation on the geodesic dome.
