A friend of mine and I took one of the 80s style fortune tellers and converted it to run off of a raspberry pi with a thermal printer so we could do custom fortunes. There’s a small rPi camera hidden in it that snaps a photo as soon as the player starts it. It’s connected to WiFi so it can talk to Amazon AWS to use their image recognition platform to identify people that have received fortunes before. The fortune it gives can be modified based on things like coming back too soon after being told to try again later or if there are multiple people in the photo. It will also pick certain people to always receive a positive or negative fortune, or even the exact same fortune.
Ton of fun at parties!
