Pictaps allows you to design a person who then turns into a zillion people dancing to music.  You just have to try it to understand.

It gives you the url of your dancing people, so English Language Learners can quickly create one, paste the url into their blog or journal, and then write about it.

It’s not “deep,” but it’s fun!

I’ve placed the link on the Examples of Student Work page near the bottom and called it Student Dancing Person.
