Easy & Fun Halloween Costumes!
I came across this link to SeeNow.com. This site is incredibly fun to play with and a cool way to figure out costume ideas if you are stuck this Halloween. What they have done is created a tool that let’s you upload a photo of yourself (black and white worked great for me) to their server. They then ask you to help them position the eyes on your photo, and then that’s it! You first pick from a wide variety of photos that they will plop your face onto. They take care of of the positioning (although you can adjust it), size and colouring. I found it worked remarkably well.
The cool part is, that your uploaded photo can stay with your session, so you can easily browse other sample with your real photo in it to quickly see all the possibilities. I took this photo for my tests and used it to generate some pretty funny pics!

I think black & white is a good pic to start with
I started with this one.
And generated these, enjoy!
