I'm making a cat themed puzzle game for my wife using NiceGUI, MindAR and some cat shaped sticky notes. Each note has a name and a secret code. I've hidden 20 of these around the house. I set up a single page app in NiceGUI to display a grid of the lost cats. When you click one it'll display their name, a clue to its hiding spot and an optional hint. 5 of the puzzles use MindAR that will display AR image cards over different art pieces and book covers in our house. I have the NiceGUI page and MindAR set up on one of my Proxmox LXCs that I use for various Flask servers.
