The “Tall Tree and the Eye” is an experimental project of AGU in collaboration with Anish Kapoor, exhibited at the London’s Royal Academy of Fine Arts in 2009. This paper describes the geometrical studies underlying the design and manufacturing of this sculpture. Using digital form-finding techniques that simulate gravity force and explicit history tools together with the study of sphere packing and curved mirror reflections, the AGU developed a geometrical model that could adapt and change accordingly to the design and structural progress from the initial stage to the construction phase.
