Are you wondering why we picked the name Fetter's Chaos for a colouring poster?: It is a tip of our superhero hat to Ellen Fetter and Margaret Hamilton who contributed to one of the most important papers in computational physics. This paper formed the foundation of Chaos Theory.

Chaos Theory is a branch of maths that looks at complex systems that are very sensitive to small changes. In a nutshell: small changes can give rise to big consequences.

This giant colouring poster is a great idea for birthday parties as well educational events and long rainy days.
