The OSXLCAU21 system is developed in order to satisfy the necessity of a detailed study in the evolution space of Rule 110, this system is coded in C-Objetive and at the moment it is available for OPENSTEP, Mac OS X and Windows operating systems (the version for Windows needs the installation of the WebObjects system for Windows).
The use of the OSXLCAU21 system is not complicated, the interface is dominated by buttons and windows. The system is able to work with all the evolution rules of order
. Nevertheless the handling of gliders is only for Rule 110; the system is still in developing process but it suitably works for illustrating the use of the phases and reproduce several complex behaviors.
Next we describe the facilities offered by the system and the operations that can be realized with them. The three versions of the system use the same original environment of OPENSTEP. The system and its source code are of public domain and can be freely downloaded from [3].
