@RULE Twolives

1. A new variety of Conway's Game of Life dedicated to RIP John Horton Conway's memory.
1. In this version, there exist two types of live cells of opposite "sign".
2. Two identically behaving "life forms" may coexist and interact with each other.
1. The rules of survival and birth are usual, but strictly symmetrical.
2. A "negative" cell survives, iff it has 2 or 3 "negative" live neighbours.
3. A "negative" cell is born, iff it has 3 "negative" live neighbours.
1. Importantly, the number of neighbours is counted as the total sum of their numerical values, which may be 1 or -1.
2. Thus, a "positive" cell may be born, if surrounded by 5 "positive" and 2 "negative" neighbours.
3. A "negative" cell survives, if surrounded by 5 "negative" and 3 "positive" cells etc.
