OK, I remembered this website last night and have been having inordinate amounts of fun with it:
http://www.morphthing.comEver get stuck trying to cast the Deryni movie, or trying to visualize a story character you're creating, because you can't think of any celebrity who quite looks the part? Maybe the closest thing you can come up with is something like "Well, I think he'd look something like Hugh Jackman, only the eyes would be blue, maybe something like Paul Walker's, except he'd need red hair..."? Well, this is a fun website to play with and see just how well those sets of features would morph together! Just as an example, here's a couple of morphs I made:

My attempt to recreate Catriona, the Lady of Llyr from ANAMCHARA (see the Deryni Fanfic section for a link to that story)
and ...

I morphed a young blond male face onto the "Catriona" picture to get an approximation of what she might look like in her shapeshifting illusion as "Kyle."
Neither is exactly how I envision them--for one thing, the eye color is still wrong, as both are described as having clear light green eyes--but the one drawback is that the morphing is limited to the existing physical traits of the photos uploaded into it. However, I think if you want to morph someone's features into a picture and that person isn't in their photo database, you can upload a photo of your own, I think. It just has to be a shot directly from in front rather than from the side, and with hair as much out of the face as possible. But the morphing is a good way to at least establish general facial structure and get an idea of what a character might look like, and sometimes you can get lucky with the coloring as well.
Now I'm off to see if I can figure out how to make my own Alaric, Richenda, Kelson, Dhugal, etc. (And yes, I've already experimented with a Duncan! *grin*)
