Twisting Light
These images are the refraction patterns formed when light passes through various shaped and formed plastics. By careful control and manipulation of the forming process semi-regular patterns and delicate tracery can be achieved. Also the integration of liquid colours into the soft plastic modifies the way the plastic hardens and hence the associated refraction patterns.

This is 'lensless' photography - here the object itself becomes the lens.
