Here are the images used in a simple applet which does nothing more than
arrange the images on the screen.
The key to arranging the tiles on the screen is a two-dimensional array
called map. Each image has an integer assigned to it as an identifier as
shown in the comments below.
<![CDATA[
//wall=0, dot=1, hall=2, tee=3, x=4, torn=5
int[][] map = {
{ 0,0,0,0,0,0,0,0,0,0,0,0},
{ 0,1,1,4,1,1,1,1,1,1,1,0},
{ 0,1,0,0,0,1,0,0,0,1,0,0},
{ 0,1,0,0,0,1,0,0,0,3,1,0},
{ 0,1,0,0,0,1,1,1,1,1,1,0},
{ 1,1,1,0,0,0,0,0,0,0,1,1},
{ 0,0,1,1,1,5,0,0,0,0,1,0},
{ 0,1,1,0,0,1,1,1,1,1,1,0},
{ 0,3,0,0,0,1,0,0,0,0,1,0},
{ 0,1,0,0,0,1,0,0,0,0,1,0},
{ 0,1,1,1,1,1,1,1,4,1,1,0},
{ 0,0,0,0,0,0,0,0,0,0,0,0}
};
Image[] sps = new Image[6];

Embedded for-loops are used in the paint method to draw the tiles.
