The wood portion of this piece was cut with a computer controlled
laser cutter in 1993. Note the burnt edges of the wood. Shown
in the photo is a painted paper figure in red that represents the activities
of the mind. In 1999, brass figures and ladders connecting the levels
were added (although not shown in the photo). The horizontal planes
contain an array of slots which accept these additions. The elements
of the minds can be changed and moved about much like in a doll house.
