Located at Central Park, the artwork is part of a major mixed-use urban renewal project to redevelop the old Kent Brewery site in Broadway.

The sculptural form of Halo is a reference to the enormous circular brewing-vat support found in the decommissioned Brewery Yard building, while the off-centered encircling motion of the ring is the re-imagination of stirrings of brewing alchemy and the tipsy effects of alcohol.

[2][5] The minimalist design, together with its wind driven motion, are intended to provide a calm setting against the hectic activity of the highly urbanised environment,[6] exemplifying Turpin + Crawford Studio's philosophy to create works which are "collaborations with nature".

[2][8] Mechanical engineer, Arran Gordon of Partridge, designed a bearing unit that uses a 12mm diameter partially stabilised zirconia ceramic ball to deliver an almost frictionless encircling motion while balancing the entire weight of the ring and arm, allowing the sculpture to pick up and create swaying momentum in winds as low as 2 km/h.

[2][9] Reflective pearlised glaze has been applied to the components of the sculpture to give a glistening glow of its surfaces after extensive research and testing with a specialist colour consultant.
