This simple drawing system uses keys as the tool bar and allows for practice with coloring in the lines using a mouse or trackpad. I created a simple coloring book program. With the keys a, b,c, and d you can choose between 4 simple shapes. With the keys 1-9, you can pic different colors to fill in the shapes. To erase what you have drawn simply select the same shape on the keyboard again. Ideas to further this drawing program would be to give the users more options in terms of brush style and shape.
Color the shapes. Use keys 1-9 to change the pen color. Use keys A-C to change the Background Shape.
