Another GPS-driven world map

OK, so i couldn't resist, too:
http://www.panoramas.de/panoramas/wwpmap/
This one is based on the cloudless 40000x20000 pixel earth image
(scaled down to 2000x1000) from the NASA blue marble project
(website quote: "These images are freely available to educators,
scientists, museums, and the public." - so i guess this is not
any kind of copyright violation...)
I used server-side PHP/MySQL to create CSS positioned animated
dots of the panoramas, and Javascript to have previews show/hide
side of the dots when the mouse pointer passes over a marker.
This should work with any IE above 5 (couldn't test with earlier
versions) and anything Mozilla/Netscape above Netscape 4.
The database supports pre-filtering (currently the filter is
hard-coded for "wwp904"). I've hacked the GPS coordinates from A
to J into it, but got tired... ;-) will wait until the list is
final, of course if the admins drop me a database readout, this
would also help ;-). Currently, it's got a problem with targets
very close to each other (i.e. if the markers land on top of each
other, it only responds to the top-most one - should build a list
of targets instead...)
If anyone wants the code for it, i'm glad to offer it to anyone
interested. There's nothing special to it, and it's badly
annotated ;-)
