XEmacs source tree fork looming -- we need a naming scheme

I am about to create the branch for XEmacs 22.0 and need a naming scheme. The best current suggestion is pig breeds and this amuses me now that XEmacs is lighter (and since 20.4 faster) than it has been in many years. Any other naming conventions to consider? Nominations should have at least 50 names to choose from and a URL with descriptions (like the wonderful Oklahoma State site we're using now) is a strong plus. For the record, the previous naming schemes used have been: European Capitols[1] 20.3 Gem stones 20.4 Goats 21.0 Footnotes: [1] And French cities when we were running out of European capitols.
