I'm not even sure that's possible with software, even if the photoshopping attempt isn't done very well. I suppose that if someone made it their life's work, and had unlimited time on a supercomputer, they might be able to do it. I suspect that if you're asking how to do it here, you probably don't have the skills (or supercomputer hardware) to pull it off. I'm not trying to be mean, I'm just providing an honest opinion.

What criteria would you use to determine the originality? A halfway decent photoshop attempt would result in well-blending interfaces between the original photo and what was changed. I suppose this would be an interesting task for someone with mad graphics and math skills.
