These sculptures are temporarily on display at Queen Elizabeth Park. They are part of a series of works based on hexagonal city planters found around Vancouver and the pattern of the human eye retina and crystal formations. Kerr worked in his studio to shape the smaller pieces of marble weighing from 5,000 to 7,000 pounds. The larger pieces (7,000 - 10,000 pounds) were carved in China under the artist's supervision. The forms are influenced by the shape and contingencies of the stone itself during the carving process. Kerr's sculptures were commissioned by the Public Art Program through a selection process for artworks to celebrate the City's 125th anniversary. The granite and inlay sculpture, entitled Mind Crystal located on the corner of Hamilton and Georgia is a part of this series of works and is a permanent artwork.

Kerr's sculptures are associated with images and forms that we see around us. His practice is to give new life to these associations through different materials and scale. The sculptures are exquisitely carved and are visually grounded in modernist architecture, art history and local cultural iconography.
