ASCII Art Network Diagram Tool or Plugin?

[42Network]

Hello. This is not an issue, but a question.

Your Obsidian intro video briefly showed an amazing ASCII art network diagram of your home lab. May I ask how you generated that? Did you use a tool, perhaps an Obsidian plugin to do it? Or was it created very carefully by hand?

Also, have you found a way to synchronize your IMAP information with OPNsense, so your list of IP addresses is always current? Or do you update by hand.

Thanks for nice videos!
