/*

CHALLENGES

1.  Add more shapes, circles, triangles, rectangles and arcs.

2.  Add colour to the shapes.

3.  Change the size and colour with your space,x and y variables.

4.  Make sure that the program stops drawing when the canvas is full.

5.  Have the drawing, loop to the top once it reaches the bottom of the canvas, drawing on top of the existing image
