Urban Data Challenge - Second Cut

The deadline for the Urban Data Challenge is on Sunday and that leaves very little time for a very interesting project.  So I'll keep this brief.

How's it going?  It's going well.

All data looks better in 3D.  It's Science.

I'll be covering this is much more detail when I submit it to the challenge web site.  For now, we're well on track and it's just a matter of what other features we can squeeze in.
