Langton's ant Or order out of chaos

This time we will talk about Langton's ant - the simple system of simple rules, but with complex behavior. Simple system of Langton`s ant is defined as :
* At a white square, turn 90° left, flip the color of the square, move forward one unit
* At a black square, turn 90° right, flip the color of the square, move forward one unit
This is so called L/R system. But what if for the one color we will have not the one direction, but the direction chain ? That is- for the white squares we will have some chain of 'LRLRR...' events and for the black squares we will have another chain of 'RRLRRL...' events ?? These events should cycle in a row. Then more interesting patterns should occure. So this experiment tests this idea of multiple direction row for the same state/color. Experiment script is here.
Results are somewhat interesting. At first, the classic Langton`s ant example-

Can we have system with shorter steps to "highway" ? Seems - yes we can. This is it:

But this is not the end. There is system which is almost "highway" from the scratch:


And finally- some exotic general Langton`s ant systems:







Conclusion
Seems that systems L/R and L/LRL is unstable and switches to stable system L/RLL.
Another conclusion is that there are some other systems that gets to the different types of "highway" - the order out of chaos.

Have fun with Langton`s ant !!
