It looks like a full length mirror until someone walks up to it, and then it starts talking to them. Animations, prompts, a countdown, and a signature screen where guests sign their name with a finger before it prints.
It’s the photo booth without the booth. No queue crammed into a curtained box, no four people fighting over a bench. Groups just gather in front of it, do something ridiculous, sign the print and take it away. An attendant keeps it running and fills the guest book as the night goes on.
The animations and print borders can carry your names, your date or your branding, so everything that leaves it looks like it was made for the event.
