As a spinoff of the discussion of category intersections on
wikitech-l, I have ported my toolserver-powered JavaScript add-on to
Commons.

The tool will add a new link beneath the category list of a page. A
click will open the list of categories of this page(/image) as
checkboxes. Chose two or more of these, and you can preview 20 files
in that intersection, or go to the toolserver to see them all.
To use, add
importScript('User:Magnus_Manske/category_intersection.js');
to your monobook.js. We can turn it into a gadget if wanted.
Cheers,
Magnus
