A friend posted this kickstarter on Facebook, which I thought might be of interest to some of you keen on languages! (note I’m unrelated to the project in anyway, just sharing an interesting concept!)
It’s a table top game in which you collaborate to create and evolve a language in an isolated community.
The Kickstarter project itself is here: https://www.kickstarter.com/projects/thornygames/dialect-a-game-about-language-and-how-it-dies
(Apparently, pasting the link on a line of its own just results in the video being embedded, so I’ve put it at the end of a line of text.)
Thanks, I didn’t realise that 
I didn’t either until I tried to post the link after having looked for it
I remembered that putting a link on its own line here gives a preview of the website so I tried that - and got the same video you had posted rather than something you can easily click on to go somewhere - so I moved it.
