Artist John Macnab is a featured speaker at the Bridges conference in Halifax in July. Bridges Organization fosters research, practice, and interest in mathematical connections to art, music, architecture, and culture. His exhibition at Studio 21 is a companion and visual addition to the proceedings.

Macnab combined his wood-turning background and engineering skills to invent a 20-foot vertical lathe capable of turning large-scale sculptures to complicated formulae. Drawing on his fascination with mathematics, science and the spiral he produces powerful and elegant works that bridge the gap between industrial precision and creative expression. This is the most significant exhibition of his recent work; showcasing wall pieces, suspended sculpture and standing sculptures of wood and metal.
