When I was a kid, we used to play board games as a family. One of our all-time favorites was always Electronic Talking Mystery Mansion, in which the players furnish a mansion with these little pieces of furniture and then search for clues as to where the "money" is hidden. It's an awesome game, and it kind of feels like a combination of Clue and a dollhouse.
At a recent family gathering, we went to play the game and discovered that the "computer" part wasn't reliably working. I joked that I could recreate the game... and a couple hours of tinkering later, we were playing again.
The project is available on GitHub, where there is a readme with installation instructions.
