An example of the ‘Reciprocal-User’ relationship would be Unto This Last’s
‘Wavy Chair’ (Figure 37) that has been made of more than one hundred
individual parts, CNC cut from plywood and put together with interlocking
joints. It has no additional fasteners. Its function is to be sat on as a chair.
However, it could also be argued that it can act as a static focus for the aesthetic
contemplation of the viewer. It can be looked at as both a work of art and as a
functional designed object.

An example of the ‘Interactive-Participant’ relationship would be Ken Rinaldo’s
‘Autotelematic Spider Bots’ (Figure 38). These robots interact with their human
observers, each other and their environment. These objects ‘see’ participants in
the installation with ultrasonic sensors at the end of an antennae-like neck.
They also have infrared sensors that allow them to see and avoid each other as
they seek their recharge station. These robots were designed in a 3D modelling
application. The custom parts used in their construction were produced in
photopolymer epoxy resin by the SLA® process and articulated with Nylon
monofilament. Their structural frames were cast from a rapid prototyped
master pattern in polyurethane. In this way Rinaldo has applied computer-
