Hyperbolic Forest

Hyperbolic Forest

This installation brings together pieces of knitting and crochet from all over the world. The Hyperbolic Forest is a tactile, atmospheric display that visualises the geometry of hyperbolic surfaces, a mathematical theory that changed the way we think about space.

A surface is hyperbolic when it looks like a saddle  — or in other words curves in two different directions — around each of its points.

Unfortunately there is no wheelchair access for this gallery.

Animator and digital artist Mike Futcher makes short films, music videos and installations. He likes to put CGI effects into real locations because ‘graphics can never match the infinite complexity of reality.’
