Are you into tech, cats or both? 

Blast Theory is a company that makes interactive art: we turn websites and mobile apps into thrilling entertainment experiences; create feature films where actors and stories respond to you in real time; design events where your phone guides you on real-life adventures through the city; and make mobile games that invite you to reimagine yourself and your future. We’ve been nominated for four BAFTAs and won the Golden Nica at Prix Ars Electronica and the Nam June Paik Arts Center Award.

We have two freelance opportunities to work on one of our most ambitious projects yet. Cat Royale explores the impact of AI on animals and features three cats living in a utopia created by the artists. The work will premiere as a delayed livestream at the World Science Festival in Brisbane on 22 March 2023. You can read more about Blast Theory, and Cat Royale, below.

About Cat Royale

Cat Royale is a utopia where cats live in harmony with artificial intelligence.

Cats will live inside a utopia created by the artists. The cats’ every need will be catered for, with spaces for playing and socialising, and spaces that are relaxing and private. They will have walkways, cubbyholes and raised viewing platforms.

And at the centre of the room will be a robot arm and a computer vision system offering activities to make the cats happier. The system may throw a ball, dangle a feather or offer a massage.

To ensure the comfort and safety of the cats, experts in animal welfare have been involved in the design of the project from the start and will guide us at each stage.

The computer vision system will try to measure the happiness of the cats and learn how to make them happier.

Cat Royale will be presented as a delayed livestream to audiences at the World Science Festival in Brisbane. Filming will start in the UK on 20th March.
