Broom handles painted matt black and suspended by string in a frame. the back ground is painted hardboard. I balanced each handle on a figure to find the centre of gravity before tying the string to the handle. Inaccuracies in my tying of the string leads to the handles sloping slightly.
The sacrificing of a degree of control is a feature of my approach to art
The strings are then tied to a grid above a frame. They can revolve until they hit another handle. The movement of the handles and the position of the viewer lead to many different patterns in 3D and here in 2D.
