Use a,d,w,s keys to move the pattern.
This beautiful pattern is made from prime numbers.
Positions (x,y) of each black pixel satisfy the following condition: x xor y - is a prime number.
There are many posibilities to generate patterns using similar approach. For example, by changing condition to the following: x xor y is divisible by 3, 5, 7, etc
What if we use these patterns as initial configurations in Conway's Game of Life?
to start/stop the game or use B, N to move to the next turn and R to reset. The first configuration, after about 770 steps becomes stable and only few intial pixels survive.
Variants of the initial configuration:
