The Story: (click on the red words)

``Once I saw a house. When I went into the house I found a present. When I opened the present, I found a TV set. And what do you know ... the TV was showing a little story about a house!''

 

The Java Program:

import java.awt.*;
public class Story extends GenericApplet
{
   int n = 0, S = 60;
   int I[][] = {{-1, 0, 0, 1},{ 0,0,-1,1},{-2,-1, 1, 2},{-1, 0, 0, 1}};
   int J[][] = {{-1,-2,-2,-1},{-1,1, 0,0},{-2,-1,-1,-2},{-2,-1,-1,-2}};

   public void render(Graphics g) {
      if (S <= 60) {                          // While still zooming:
         int width  = bounds().width , x = width /2;
         int height = bounds().height, y = height/2;
         g.setColor(Color.white);
         g.fillRect(0, 0, width, height);     // clear the background,
         g.setColor(Color.black);
         g.drawRect(x - S, y - S, 2*S, 2*S);  // draw box and lines,
         g.drawLine(x+S*I[n][0],y+S*J[n][0],x+S*I[n][1],y+S*J[n][1]);
         g.drawLine(x+S*I[n][2],y+S*J[n][2],x+S*I[n][3],y+S*J[n][3]);
         S++;                                 // increment the scale.
      }
   }
   public void doClick(int i)  { // on user signal:
      n = i;                     //   set image state
      S = 1;                     //   set scale=1 to restart
   }
