I didn't get to work on my old CGI app from 2002, but I did find a 
couple of the Proof of concepts I did before it, that still work . . . 
Kinda fun going and looking at things again too.

*http://pwultra5.ci.stpaul.mn.us/cgi-bin/drill/drillR10.pl (no debug info)
http://pwultra5.ci.stpaul.mn.us/cgi-bin/drill/drillR11.pl (with Debug stuff)

*Just click on the images to zoom to that spot and center on it.  Keep 
clicking, the last level just recenters on the clicked point.

You can still see the tiling artifacts in the messy seams between tiles, 
I remember I had a tough time getting the edge to line up correctly with 
the Tiler that I built.

Hmm, kinda fun going down memory lane on this . . . .  Anyway, I'm done 
on this Thread I think  :c)


P.S.  I can work on the original App and fix it if anyone is interested 
in seeing the final.  I used these tests to launch some other rather 
nice Web Products from.  There will even be an announcement soon of our 
OpenSource project that was based in part on this work.  Another week or 
two I think.
