Tag Systems
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
A tag system consists of a sequence of elements each represented by a color (here there are two colors). Each step of the evolution is determined by applying a rule that drops a particular number of elements from the front of the array generated on the previous step and appends a certain number of elements determined by the composition of the dropped elements.

Details
In the controls, "dropped" means the number dropped from the previous array in order to determine the next step in the evolution. The value "1" means the first set of rules as described above and value "2" means the second set of rules; "zoom" changes the number of pixels per block.
Tag systems are described in S. Wolfram, A New Kind of Science, Champaign, IL: Wolfram Media Inc., 2002 pp. 93–94.
