Interactive Experiences and Experiments demonstrating the impact of various forms of Representation

First-Example_L4_N16_Twinkling Nodes [ Applet ]
This Java applet demonstrates how system dynamics can be represented visually by twinkling nodes (e.g., Kauffman, 1993). It includes a perturb button and good text.

Using Sound & Nodes to Represent Dynamic Pattern [ Applet ]
Good instructions and text. Uses a system with short basins (L=4, L=8). Gives direct experience with hearing dynamic patterns. Includes visual representation with twinkling nodes so that a direct comparison of hearing and seeing patterns can be made.

Using a Visual Historical Trace to Represent Dynamic Pattern [ Applet ]
Same system as the one directly above, but represents system dynamics as a visual historical trace to allow you to compare (based on your experience with the above applet) these three forms of representation (twinkling nodes, sound, trace).

Twinkling Nodes & Sound Representations for a dynamic system with long tributaries [ Applet ]
How do tributaries effect our ability to perceive dynamic pattern?
