This is an earlier post. I've added a few more sites to this list, so I'm reposting.My kids and I had so much fun with a Christmas site I found a few days ago, where you can upload photos and put the heads of people (or animals, as my oldest did) on dancing elves.
And it was viral. They sent it to their friends, who sent one to their friends, who sent one to their friends - and on and on and on. It was a great way of spreading Christmas cheer.
So I got to wondering what else might be out there for kids (young and old) that might be fun. Here are some of the gems that I found. If a site was too heavy on advertising, I didn't include it. The Elf Yourself site is the one my kids and I had so much fun with. Have fun!
