This piece by Mathieu Lehanneur is incredible! From designboom:
during its international gardens festival — on from now until november 2016 — french designer mathieu lehanneur brings a ‘liquid marble’ installation to the courtyard of domaine de chaumont-sur-loire centre d’arts et de nature in france. ‘petite loire’ highlights the ways in which marble, water and light come together to evoke a dynamic feeling of a river in motion. comprising a single piece of hand-polished green marble designed using 3D software, the surreal object reproduces the effect of wind passing over the surface of water, transforming an ephemeral moment into something solid. ‘petite loire’ — a continuation of lehanneur’s ‘liquid marble’ series — explores the potential of using algorithms to manifest a transitory moment in time.
