Cathryn;

All of those are doable.

What I had in mind was setting up a database of all events from some particular area and looking at it in 3-d over time.

It's an extension of the hologram I had made of the Loma Prieta sequence, but those guys had a LOT of computer hardware to play with. It was the cover art for the BSSA special edition.

Any way, with a PC the best I can do is a 3-d wireframe which can be examined from any angle for any time period and with any given duration for the quakes to be visible.

But you'll need a PC to run it.
