Art installation content

OPEN AI®️ — treating the 10 Corso Como Rooftop not as architecture but as an interface with the sky — a field where air moves freely and carries information across space. Based on the premise that air and water are the last truly free elements, the installation is structured through distinct “pillow areas”, positioned according to the cardinal directions of the wind.

Each pillow is nano-embedded with molecular compositions that correspond to light, temperature, movement, and time, creating an atmosphere that changes throughout the day, and an invisible choreography of perception. The existing garden provides an organic infrastructure wherein artificial molecules are introduced by Tolaas, creating invisible friction between the organic and the engineered. Guests are offered water infused with molecules, acting not only as refreshment but as a continuation of the project’s elemental logic: a carrier of taste, memory, and life.
