Massive Datasets/Models

[render_dude]

I'm looking for any pointers/links/contacts to acquire some massive-sized (>100 million elements) models and datasets to feed my renderer I'm writing for my Ph.D. For my early test scenes I've either procedurally generated them ( city scene > 160 MegaPolys) or created through replication (1600 copies of the stanford bunny). To appease reviewers from an earlier submission, I need more variety to test against.

I currently have:
1. UNC Powerplant
2. San Miguel
3. Lucy (+ several others from the stanford model archive, but none from the Digital Michelangelo Project)

I'd like to get:
1. Boeing airplane model (contacts?)
2. Livermore Richtmyer-Meshkov instability Isosurface
3. ????

Any help is appreciated.

Thanks,
Mark
