Use a,d,w,s keys to move the pattern.
This beautiful pattern is formed from prime numbers.
Positions (x,y) of each black pixel satisfy the following condition: x xor y  is a prime number. There are many possibilities to generate patterns using a similar approach. For example, by changing the 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? Step: initial
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:
