A CA- Applet
Despite being one dimensional, the CA may extend also into the second dimension, which is illustrated by the following applet. Initially it depicts a one dimensional CA. As one clicks on the "longer" button the CA broadens and becomes two dimensional. Initially only one CA state at a time may interact with the environment. As the CA widens more states have the option to interact.
Click "plant" to plant a new zygote. Initially the zygote differentiates until becoming a mature CA with a period of 46.
