This post originally appeared, in a somewhat different format, on my old website, "Atomic Robot's Freedom Force Gallery" at www.geocities.com/robotatomic. That website is now offline, although an archived version of it is available at http://www.oocities.org/robotatomic/index.html. Much of the information is now out of date, and many of the links may be inactive, but I'm keeping it online here for posterity's sake.
Update: September 12, 2003
I've created a skin of Catwoman for Bobby 69's batgirl_classic69 mesh.
It works out pretty well for Catwoman, except for the spiked fins on the
arms, and the bat shaped cape. It'll do until someone makes a
dedicated Catwoman mesh, though.
