The first mani­festo work from the Solar Lab, the projec­tion displayed on the west façade of the Musée cantonal des beaux-arts in Lausanne is powered primar­ily by sunlight. As a result, it is inter­mit­tent and weather-depend­ent. Studio Lemer­cier has developed an innov­at­ive daytime projec­tion system: helio­stats ‒ i.e., motor­ised mirror systems that track the sun’s move­ment ‒ chan­nel its light through multiple lenses to produce shapes. Their creation involved numer­ous complex steps, includ­ing 3D soft­ware, algorithms and metic­u­lous machin­ing, thus blend­ing tech­no­logy and crafts­man­ship.
