When we were children, we often used to draw. And sometimes as we weren't able to erase our drawings we decided to tear the paper in pieces in order to start again!
Drawing and Coloring games for children will finally settle the problems of purchasing paper, pencils or felts that no longer work.
Children (and even olders) will be able to let their imagination express itself by designing, creating and inventing visual shimmering colors. And if make something wrong or that does not suit to them, they simply have to cancel it.
