A piece of very thin paper tissue (actually Whatman lens cleaning tissue - used for cleaning microscope lenses without scratching) viewed by polarised light microscopy. The crystals that form the fibres due to their regular arrays interfere with the light path and 'twist' the light to give the colours shown.
Blank inside so perfect for any occasion.
