InformationSpace is a causal set exploration tool. It allows you to
visualize, and explore in 3D,  2D causal sets such as those found in
John Conway's game of life (The third dimension is time).
InformationSpace now supports visualization inside Croquet. This makes
exploring your visualizations much more pleasant and productive versus
using the older Balloon3D API.

You can also find informationspace in SqueakMap.
