SOLART2 sundial sculpture by artist MA2F

SOLART2 by artist MA2F

UNESCO has declared 2015 the International Year of Light and Light-Based Technologies (IYL-2015). For sundialists, the inauguration of SOLART2 on the June 2015 solstice may be the highlight. SOLART2 is the largest IYL-2015 artistic sundial project in Europe. It is located in Rivesaltes at the northern entrance of Perpignan, France.  It was initiated in 2013 as a strong symbol of sustainable development. Artist MA2F (Marc-Andre 2 Figuères) is constructing the sundial with an incredibly large gnomon created from a double metal bar with numbers silouhettes cut into the structure.   The dial is meant to illustrate the flow of matter and energy, projecting a continually changing shadow of numbers onto the dial face during the progression of solar time.    The edges of the gnomon are painted red "as a visual value and mastery of light".  You can see a video of the dial at:

The International Year of Light and Light-Based Technologies (IYL-2015) is a global initiative adopted by the United Nations to stress enhanced global awareness of and increased education in the science and technologies of light are vital for addressing challenges such as sustainable development, energy and community health, as well as for improving the quality of life in both developed and developing countries ....  With UNESCO as lead agency, IYL-2015 programs not only promote light in the modern world, but celebrate milestone events in light and optics.
