Interactive Table Cloth

At first sight it seems that this is a normal table cloth, but in time it reveals something hidden.
It basically consists of a programmable display sheet (OLEDs with touch, temperature and light reactive sensors) covered with a fitting table cloth (translucent, water resistant) that’s placed on a table with conducting contacts to power the display.
Therefore any interaction, wanted or unwanted, generates a unique image or patttern based on the initial shape of the object in contact with the table cloth.
