Art Games for students

I'm currently working with a student population that has limited use of their hands. I find they really enjoy online art projects of the drag and drop variety. They can accomplish them more easily while still addressing formal issues.

I've compiled a list of some neat sites.

Mr. Picassohead - create a Picasso-like face. http://www.mrpicassohead.com/create.html

bomomo - abstract art generator. http://bomomo.com/

Collage machine - creates collages. http://www.nga.gov/kids/zone/collagemachine.htm

Joseph Cornell boxes http://www.artic.edu/aic/education/CC/

American Naive Painting generator - http://www.nga.gov/kids/zone/faces.htm
