You seem to look for „digital signage“. So rather Google for that, imho. We use https://www.xibosignage.com to show some stuff, you are relatively free to put what you want where you want and can do that centrally for one or a lot of displays.

These are not live updated, but I sometimes have one up and use a browser plugin to refresh the page every 30min

I think the source code on how the images are generated are open source. Maybe you can download the source code and make a live page or four.

Having read your comment I think I understand what you are looking for: fancy dashes available to the public to serve as inspiration for your team.
