Here’s what Clay looks like:
Here’s what Warren looks like:

Kevan has named it:
extispicious, a. [L. extispicium an inspection of the innards for divination; extra the entrails + specer to look at.] Relating to the inspection of entrails for prognostication.

Matt,
interesting, but not as wild as the old Hotsauce fly-thru application from the Apple Research labs a few years back. With that you could not only visualise your file structure, you could ‘fly’ through your drive.
Cheers

It would have been nice if Kevan had at least talked to Joshua; it’s been unexpected load on the server, and it’s not using the provided API, but screen scraping.
If it used the API, and played nice, it could do clustering too.
