A display article (10) includes a plurality of display areas (12, and 13a to 13c). Display areas adjacent to each other differ in at least one of an average hue, an average brightness and an average chroma and a first object to be displayed (21) is formed by a combination of the plurality of display areas (12, and 13a to 13c). At least one of the display areas (12, 13a to 13c) includes a Fourier transform hologram (20R, 20Y) configured to convert incident ray from a point light source or a laser light source into a second object to be displayed.

The invention relates to microphone accessories, methods of using microphones, and a microphone. The accessory has at least one body having at least one display face for displaying at least one communication; an attachment formation for operatively attaching all or part of the accessory to the microphone; and a displacement arrangement controllable to displace all or part of the accessory automatically in a pre-determined or pre-selected manner relative to the microphone such that, in use, the at least one display face is correspondingly automatically displaced rotatably relative to the microphone. The invention also extends to an associates method of using a microphone by providing an accessory on a microphone flag and displacing the same relative to the microphone. Moreover, the invention extends to a microphone operable to displace a microphone accessory relative to a longitudinal axis of a handle thereof.
