this is our first aproach to the idea of a 3d navigator for your destop
( the real one, the wooden ). you have to move a pen over a projected
horizontal section of an architectual plan. if the pen will rest over
one of the rooms a 3d view of this room shows up. you can turn around
by moving the pen within the room.
