Looking for an interactive art site for children? I found a great one! The National Gallery of Art for kids is full of fantastic artistic journeys. They can create their own portraits or landscapes with folk art images.
If your children like to take photos, they can also explore using and editing photos with a digital camera. Plus design their own abstract images or furnish a 17th century virtual dutch dollhouse.
Of course they can also learn about all the great works of art as well and the history of the artists who painted them. This site has many layers to explore!
My son's own art work has become much more detailed and yet original still, since I added this website to his favorites!
