The VNB walker engine is fairly simplistic in it's design...

Instructions...

Move the mouse to the edge of the picture and the cursor will turn to a pointer when it is possible to move in that directions.

Not all pictures allow motion in all directions.

You have to wave the mouse around each picture to see which way it is possible to walk.
