There is no simple way to get the rules for that CA. However, if you press Shift+Space, you get an alternative representation of the hash that lets you re-seed while keeping the same rule: https://skulk.org/cell1d/#c2:3:1,0,0,1,0,0,1,0:12;120;115,15...

This format is ad-hoc, but you can read it as such: The first number after #c is 2, which is the number of states. The second number, 3, is the size of the transition window. This tells us that this is a standard 1-d CA. The next 8 (2^3) numbers is the transition table. Interpreting it as binary (in reverse), we get the number (and rule) 73. http://atlas.wolfram.com/01/01/73/

The next couple of numbers are the colors used, and the final number is the seed. You can change this and the rules/colors will remain the same but the top row is re-randomized.

BTW: here is my favorite. I call it the coral reef: https://skulk.org/cell1d/#s54509032
