Got inspiration from https://github.com/gerusz/dm_loading_screen to make this. This is much simpler than that one.

Use this when you (the DM) are busy thinking of something. Give the players a loading screen!

To run it open up the directory with an HTTP server. If you have python3 installed it is quite easy:

python3 -m http.server

Run that in your terminal with this directory as the cwd. Then just navigate to https://[::]:8000/ on your web browser.

If you need help, feel free to ask :)
