Anything that carries meaning can be a Communication Object (CO) - a bottle of shampoo with name and description, your own tatooed body, red card, white flag, smoke, medal, shoes, hat etc.
But here, we are talking about another, special kind of Communication Object (CO) - our own version, both physical and digital, continually updated and expressed according to the purpose.
Think of it as a container - holding text, images and other forms of data.
A good example of how it can work is a
›Personal Introduction Note (PIN).
Consider, select and store relevant information about yourself in your PIN CO - in digital form, as a layered image, which is updated and expressed (printed or emailed) in as many versions as needed.
