Nature 13 - Tree of Photosynthesis, The National Art Center, Tokyo, 2009
"The aims of Tree of Photosynthesis visualize the photosynthesis of plants, in which chlorophyll is the catalyst.
"Tree of Photosynthesis" was realized for the first time in autumn 2006, two and a half years following its conception, with full support from the French City of Argenteuil, thanks to their understanding of the importance of the project, and every day the tree was allowed to do its work of reviving photosynthesis. The discs which changed color in reaction to changes in the weather were attractive enough to awaken the curiosity of passersby, who ended up watching them for the two-month duration of the show. It would have been worth this artwork being amongst these people if, by their interest in the plastic discs, they had been brought to an awareness of the daily natural metamorphoses of the tree itself."
