The first of the five "lenses" forms a bright and transparent lobby, with café, art library and bookstore, inviting the public into the Museum and encouraging movement via ramps toward the galleries as they progress downward into the garden. From the lobby a new cross-axis connects through to the original building's grand spaces. At night the glowing glass volume of the lobby provides an inviting transparency, drawing visitors to events and activities. The lenses' multiple layers of translucent glass gather, diffuse and refract light, at times materializing light like blocks of ice. During the day the lenses inject varying qualities of light into the galleries, while at night the sculpture garden glows with their internal light. The "meandering path" threaded between the lenses in the Sculpture Park has its sinuous complement in the open flow through the continuous level of galleries below. The galleries, organized in sequence to support the progression of the collections, gradually step down into the Park, and are punctuated by views into the landscape.
