On gimp-users today someone asked a question about the availability of panorama tools for the GIMP.

I had previously searched for and found such a plug-in, but it had been a couple of years, so I went on a quick web search to see if I could find the one I remembered.

I uncovered this massive community of people interested in stitching tools, with a very active mailing list and several applications (some GIMP plug-ins too) - I must admit I was surprised, since I had never heard of most of these applications before.

Here are the results of that "quick" search, for posterity.

• The original set of tools I remembered was pandora. It has its own webpage with a more recent version to download: http://www.shallowsky.com/software/pandora/

• Or it might have been Panotools. The home page for Panorama tools is http://panotools.sourceforge.net/ and it is GIMP 2.0 compatible.

• However I found a whole mailing list which is *very* active on panotools frontends - http://www.email-lists.org/mailman/listinfo/ptx

• There are many programs mentioned on that list, among them hugin seems to be the most reccommended: http://hugin.sourceforge.net/

• And the enblend program: http://enblend.sourceforge.net/

• And finally autostitch: http://user.cs.tu-berlin.de/~nowozin/autopano-sift/

The ptx mailing list has about 100 mails a month, primarily from hugin developers. This is a great model for "themed" software - different packages whose functionality complements each other.
