What even is it? I read the github repo but that explains nothing about what it actually is.
Yeah I had no clue what this site was until reading the comments. I saw you could move things on the page around, then gave up because I had no idea what the point was. I didn't even find the github link until I saw your comment and decided to play around more.

From the Github Readme[1]:
Automat's objective is to be able to semi-autonomously play a variety of games. It's the first step towards a more general environment for interacting with computers.
Currently Automat's functionality is limited to keyboard macro recording & playback. It's fairly unstable but if you're lucky and it runs on your machine, it can be useful for automating some basic actions.
