A badge has a backing (1) of PVC sheet loaded on its front surface with microbeads (2) to render it reflective. A front sheet (3) of transparent, flexible PVC sheet is welded to the backing around their periphery (4) and at lines (5) extending in from the periphery. Further lines of connection between the front and backing sheets are provided. The space encapsulated between the backing and the front sheet contains: air (15), colourless liquid (16) and dyed liquid (17). These three fluids take up random shapes, which can be changed by pressure on the areas presently containing the various fluids.
