Fastmail has one of these in the entryway to our Philadelphia office. It's been a lot of fun playing with the API — so far, we've made an integration with our company's chatbot [1] to manage "board tokens" [2] which allow folks to post to it (without clobbering each other's designs); a web UI to create designs which can be posted using the bot; and a 'vesta show' command, which creates a composite image of each cell of the board to represent the current board state (e.g. [3]) so that our colleagues in Australia and elsewhere can participate.
It's a lot of fun!

[2] Token in the "arcade token" sense, not "authorization token"
