Dániel Erdély has developed the Spidron system for 26 years with the help of friends and acquaintances, scientists, artists, artisans and private personae without having any institution supporting him. His first relief of spidrons was made for the form study class of Dr. Rubik Ernő. Presently spidron is being developed and researched at many parts of the world.

The geometric system of the artist called spidron is a real mathematic and interdisciplinary innovation that is very promising on many fields of contemporary fine arts as well. It achieved significant success at many international mathematics and artistic forums of the world.


A complex geometrical shape constructed from sequences of equilateral and 120 degree isosceles triangles has led us to a number of conclusions in various fields of mathematics. From plane tessellations through space-filling solids all the way to dynamic deformations the complex has revealed a number of strikingly interesting properties.

With the assistance of Prof. Lajos Szilassi we have succeeded in creating the mathematical model that describes the spatial movements of this complex of (rigid) triangular faces called the Spidron system.

The Spidron is a planar figure consisting of two alternating sequences of isosceles triangles which, once it is folded along the edges, exhibits extraordinary spatial properties. The Spidron can be used to construct various space-filling polyhedra and reliefs, while its deformations render it suitable for the construction of finely adjustable dynamic structures.

photos were taken during the presentation and arranged to gif animation

Spidron arms also have fractal properties which can be used
to create planar as well as spatial compositions
