Convert a Black and white television to Colour!

This is a 3d model for the wheel employed in the Butterfield method of colour television. In reality, it is not colour television, but an optical illusion. The wheel need yellow, magenta, and cyan colour filters, and a sheet of black paper. put the wheel on a motor, put the wheel infront of a black and white camera, and hook the camera up to a black and white television. Spin the wheel up to speed until a suitable illusion is seen on your screen. For more information, google Benham's top. This device may cause seizures.
