Generative Systems refers to systems that use a few basic rules to yield extremely varied and unpredictable patterns.

Video game designer Will Wright and musician Brian Eno.

Generativity of a system is premised on five principle factors:

1 How extensively a system of technology leverages a set of possible tasks;

2 How well it can be adapted to a range of tasks;

3 How easily new contributors can master it;

4 How accessible it is to those ready and able to build on it; and

5 How transferable any changes are to others, including non-experts.
