Children can create a painting and then post their picture in the art gallery of their choice for others to see. The galleries to choose from are:
This interactive game allows children to deal with the human figure and their surroundings in art pieces. The different elements and images the children can use are all from paintings done by American naive artists. Just to let everyone know you will need a plug-In called Shockwave Player. 
Teaches children how to compose different still lives, they can then paint or draw these still lives. This will teach them composition, subject matter, and help them learn how to paint or draw while also teaching them the works of master painters. Children can also change the lighting in their image as well as the darkness of the shadows, the placement of objects, which objects to choose and the scale of the objects.
This interactive lesson allows children to create different textiles, textures and patterns using symmetry. If they are learning about Islamic art and the tiling patterns they create they can then mimic this using wallOvers. They are given a virtual wall with grids, when a child draws in one box it mimics it in all the boxes creating a pattern/ textile.
This interactive lesson allows children to use different tools to create abstract and non representational pieces of art. This can be a good practice session or lead up to a lesson on Abstract, Abstract Expressionism and Modern Art. Perhaps learning about Jackson Pollock, Kandinsky, etc. 
This interactive art game/lesson is for children of all ages. They choose from a ton of images of different objects or people and then put them together to create characters and pieces. This can be used for a lesson in collage and using outside objects or clippings from magazines to create a piece of art. Different tools are scale, shadow, level, flip, turn, and build.
