3D Design 
Chapter 10 Summary

This chapter summarizes the manipulation of time and motion through a change in design. It then gives examples of kinetic sculptures, which are sculpture designs that incorporate patterns of real movement. According to the chapter, time is change and all change is motion. The manipulation of this change within a design makes it kinetic. 
A lot of change and motion involves cyclic time, which is a rhythmic nature involving a circular or rotary motion, such as the earth’s rotation. A rhythmic nature is something that rotates to its initial point. As humans, we relate time by a rhythmic nature such as our calendars and our changes within the seasons. So, cyclic time and rhythmic nature makes sense to us. 
The chapter then explains how designed objects work through space and time by an operator. Objects work through an operator by the behavior of the operator and the range of motion made possible by an object’s design. An example is a car engine and how it operates. Some objects incorporate shortened existence into their design such as eroding, explaining and collapsing to their end. 
As forms and shapes enliven space, events activate time. There is a manipulation of space and time to find the meanings of where art and design take space. I think understanding this manipulation will help us in our final 3D assignment which involves the manipulation of motion and operating a design by a mechanical operator.
