Image Morphing in Gimp

Does anyone know of a plugin for vector guide based, etc. morphing of images in Gimp or any other layer based application for image morphing that a Linux user can get a hold of?

There’s a page that list all the plugs here
http://registry.gimp.org/index.jsp
and a search for morph turns up this
http://registry.gimp.org/list?name=morph
but I’ve never tried any morphing myself. Maybe there’s something useful to be found there.

Thanks Marty!
