Type Hands-on, inmersive
Topics Fractals


A two-station full-body interactive in which a camera captures and processes the (moving) image of each visitor, creating a fractal made up of repeated but successively smaller images of the visitor’s head and torso.

Activities and user interaction

Move your arms and your body around. See successively smaller copies of yourself combined to make a dynamic fractal tree that sways in response to your motion. You can combine your fractal with your neighbor’s to create a tree that you both can affect. You can also incorporate different backgrounds based on the changing seasons of the year!

Mathematical background

The fractals in Human Tree are binary fractals, in which each fork is composed of two branches, and represent only one type of the many fractal patterns that appear in nature.

History and museology

Human Tree has proven to be one of MoMath’s biggest hits, an immediate experience that delights all ages and is the source of countless selfies.
