Clay Yourself! is a fun avatar maker from Hotels.com.
It was originally used as part of a contest that has since ended,
but you can still create a clay version of yourself using this site.
You choose a face shape, eye type and color, eyebrows, nose, mouth, ears, hair style and color, jewelry for women, accessories for men, hat, glasses, shirt type and color and from any extras.
Once your clay avatar is complete you can download it.
This would be great to use at the beginning of the year when you are having students introduce themselves (or each other) or also when doing a character study.
So many options for such a fun activity!
