This post is a summary of a paper written with Mathieu Huard and Micheal Eigensatz from Evolute presented at AAG 2014 at UCL in london. Both of them were at the origin of the optimization idea and invited me to play with their new toy. The post will present mostly the second part of the article which I was mostly involved with , using some extract from the article itself. Read more

These pictures are close up of a mundane glass vase. It shows how the use of glass could be if one would think of it differently, even in the building industry. The potential is here, glass as water. Read more

Shading / Lighting grid


Shading in buildings has become an unavoidable topic. On one side, light is needed and looked for and buildings tend to be as open as possible, meaning as transparent. On the other side using too much glass implies some potential heat gains that are too costly to deal with in the summer, whereas in the winter they are welcome… Read more

Shading/Light Model


This post is a follow up of the post Shading and Light grid, presenting the fabrication of model of the light grid system. The images are extracted from a paper presented at the Design Modelling Symposium Berlin 2013. Read more

Light eXplosion

This serie is before all the fruit of faith, the discovery of a white shadow coming from a piece of mirror paper in a trash filled with sunlight.Theses white shadows or « Light explosions » according to Bernardo Zavattini were in fact some caustics, Read more

Philip Ball relate in his book Flow, the fascination of Leonardo da Vinci with vortex. After him very few representation of water can be seen in the art world, apart may be, Turner and the impressionist especially Monet, who were more focused onto other aspects of water than just its movement,  the reflection on the surface of water.

Still flow


It is easier to write about an attraction to “moving reflections on the surface of water” than about an attraction to herbs, barren trees and ground. Read more

Death ray

In 212 BC during the siege of Syracuse, Archimedes is known to have constructed a “burning glass” to set the Roman warships afire. An array of reflective surfaces (mirror or reflective  shield) was orientated toward one focal point concentrating enough energy so set the enemy boats on fire, ei a Death ray. Read more

Winter or early spring ,the leaves are still gone on the bushes and trees.

The sky is white or clear blue.

Everything is greyish, letting just the branches appears as lines with an amazing density in a totally saturated field. Read more

Earlier this year, I started a serie of pictures of the surface of water of the canal Saint Martin in Paris. I was looking for wave patterns to inspire some glass design,something quite specific about the various ripples on the water surface under different wind conditions. Particularly when a fast wind gust superimpose itself with small ripples over bigger ripples pattern Read more

Constellation – Flow

This is a variation of the Constellation Panel. The same panel is used as a roof. Above this panel there is a glass plan which can contain a thin layer of water. When a slightly  wind ,activate the surface of the water, creating some ripples , the projection of light move accordingly. Read more

Light X Making off

The pictures were mostly taken with sun light, although a few were taken with parallel artificial light. They are all reflective caustics, using mirror paper with a texture. The texture were produced in a somewhat random way and then tested with light, back and fourth. Read more
