The sculptures MANNA MACHINE are photobioreactors in which algae (Chlorella vulgaris) grow. The tubes and hoses form a drawing in space and are used for photosynthesis, similar to the leaves of a plant. The resulting biomass is filtered, dried and processed into pigment. Fixed in oil or resin, the algae pigment becomes the painting material for the painting series HARVEST.
