This collection of seven sculptures, along with a versatile modular system, is a celebration of mathematical beauty and physical engagement.  Each piece is an exploration of minimal surfaces that represent efficiency and elegance. Children can climb and explore these forms, engaging with geometry in a physical way.  Currently, all of them stand as proposals. I hope to bring these concepts  to life, creating tangible experiences that will enrich our planet.  I welcome any form of contact, be it for inquiries, support, or partnerships, that can aid in making these visions into a reality.
