Twister starts life as a parametric algorithm. The parameters govern certain aspects of the shape allowing infinitely many variations to be formed. The algorithm is then interpreted to produce millions of triangles describing the geometry of each piece. This is then sliced and 3D printed using a desktop 3D printer. Each vane is then carefully painted by hand and mounted in exactly the correct orientation to produce the final piece.
Twister won the Making Art 4.0 international technology aided art contest in 2017.
When viewed from the front the contrasting colours show spirals twisting into and out from the centre. But twister looks different from every angle with the curved surfaces producing a variety of shades and patterns of colour.
