Fascinated by the mystery and beauty of nature, and in particular by its mathematical and geometrical characteristics, I try to show my sensitivity and my inner questions through the creation of objects which demonstrate these concepts.

My preferred tools are fractal art, amazing polyhedra, geodesic structures as well as tensegrity.

I also like transgression, and often build collapsible objects, which should not formally be so! Decorative stars are a good example of this.

This new star, derived from "implausible star" ( presented at 2017 Joint Mathematics Meetings) also looks like a Great Stellated Dodecahedron. It is obtained by spatial combination of five regular tetrahedrons, who do not touch each other. They are held in place by an icosahedron of fishing line strands, now attached to the middle of flexible boughs (instead of the extremities), giving a particularly aerial shape.

I use the structural principle of "Tensegrity" based on the use of isolated components in compression inside a net of continuous tension.
