A GUI (Graphic User Interface) is an interface between the human user and the computer that uses graphic objects such as buttons, menus, etc. and mouse input to navigate and make changes.

GUI's require event handlers in code to define what should happen when a mouse click occurs in a specific region (such as the region defined by a rectangular button).

In the CodeSkulptor Docs, go to Graphics Modules, then SimpleGUI Module - Canvas to see what commands there are to draw shapes on the canvas.  

Make a program that draws a picture of a character, or a scene. 

You can use 

• circles
• squares
• triangles
• polygons
• Rectangles

You should draw at least 10 shapes, and 3 different colors.
