Chaos Applet

Before you start coding, figure out how to make a method that given two x,y cordinates (ints everything), draws a dot (small circle) on the screen at the MIDPOINT between those spots.

If you follow these steps, something cool happens.

• Choose three corners of a triangle - fairly spread out. Number them 1 to 3 in the code.
• Randomly select a point on the screen. (x,y)
• Choose a random number form 1 to 3. Based on which number you get, plot a point halfway between the random point on the screen and that corner of the triangle. Make the random point take on the value of the midpoint.
• Repeat this MANY times (take the "random" point - the random point is now the midpoint of the corner and the last point and not exactly random any more-, randomly choose one of the three corners and plot a point halfway. Copy the new midpoint into the "random point").
• It is more interesting if you put a delay in between the plotting of the points. They you can see the shape appear.

A possible extension: Allow the user to choose the co-ordinates for the corners of the screen using input boxes and a single button on the screen.

Another possible extension: Use a different number of corner points. (Say four or five.) You could even allow the user to choose the number of corner points.

(Marking assumes that the items in the previous levels, such as "Comments", are also complete in the higher levels).
