Rotobooth is a photobooth powered by an Arduino and connected to a rotary phone, allowing users to take four photos that are then sent via SMS with links to their images on Flickr. The project was inspired by the team's desire to create a fun and interactive experience, with the first prize being a weekend of hard work and play. The Rotobooth uses Twilio for sending photo links via text message, leveraging the team's prior experience with phone hacking and Asterisk. With plans to expand the product to include remote locations and new features, Rotobooth aims to bring people together through photography.
