This is an old project, but by some miracle it's still working and I woke up this morning wanting to celebrate the things I love more.

This Inkplate e-ink screen shows Conway's Game of Life, seeded from tarpits I have on the Internet. The tarpits are programs on my computer that superficially look like insecure Telnet and Remote Desktop services, but actually exist to respond super slowly and make bots scanning the Internet 'get stuck'.

When a bot connects to the tarpit, the data it sends gets squished into a 5x5 grid and 'stamped' onto a Game of Life board. Data from a bot at the IP address 1.1.x.x will get stamped on the top left corner, data from a bot at 254.254.x.x will get stamped on the bottom right corner.

Conway's Game of Life, a set of simple rules that govern whether cells should turn on or off, updates the display once per second. The result is that bot attacks end up appearing as distinct 'creatures', that get bigger and more angry looking over time (as their centre is updated with new data). After the attack finishes, the 'creature' eventually burns itself out.

Despite that description, it's a really chill piece of art that doesn't draw too much attention but I can happily watch for a long time.

Credit for the idea goes to @_mattata, I had been wanting to make a real-life version of XKCD #350 for years before seeing his Botnet Fishbowl project.

@brett That is so cool and awesome! Something that interacts with the outside world yet never gets boring to watch.

Awesome project!

By the way, how frequently do you see bot attacks on there, or are they pretty much continuous?

@NeoFox Thanks! It's almost a continuous stream of attacks, though the nature of the Game of Life means that a gap isn't immediately noticeable

@brett just a thought; with those fancier multicolor eink displays, it would be interesting to highlight pixels changed by an external ping in a different color than if it were updated following the game of life.

Although I don't think multicolor eink displays support partial refreshes or such clean transitions as they do some fancy stuff to show the colors

@brett So all the changes caused by attacks are in, say, red, so you could see when attacks were happening in real time
