TRANSFORMING POLYHEDRA
At the 2010 Bridges Art Exhibition in Pécs I have presented 3
transforming polyhedra: the cube, the rhombic dodecahedron and the
triacontahedron.
For this exhibition I would like to present three objects that show
their movement: from very slow to fast pulsating.
The sphere is divided in 8 parts. They are connected with 24 axes
of rotation.
A diagonal spring connects oposite parts.
A vertical sliding action opens and closes the sphere.
The form is produced by rapid prototyping out of one piece,
including the hinges.
The dodecahedron on the picture is suspended in the air with a
thin wire. The wire is attached to a metal spring.The edges of the
dodecahedron are provided with hinges, 48 in total .
Pulling the wire up and down opens and closes the form.
With the right frequency the form starts "pulsating". The change
in volume reminds of a fast beating heart.
The situation can be reconstructed in the exhibition with simple
means so that visitors can experience the fenomenon.
The edges of the cube are provided with 2 hinges, 24 in total.
By turning a lever a diagonal axis moves slowly up and down.
The cube open and closes.
