Calling it adorable without a front and center screenshot is an odd choice.

I visited the README solely because “adorable” was a provocative word and I wanted to see a screenshot of said adorableness. Give the people what they want!

My interpretation was that it was simple, code is easy to read and it does one simple thing.

This launches a new instance of a command of your choosing for every new connection. That does not really seem like casting to me more like a remote shell, but it is adorable in some ways.
