Each of a cluster of computing balls (1) contains within its housing (3) a photosensitive device (51) for receiving light from a light source (5) and converting it into energy to power a processing chip (2). There is thus wireless transmission of power to the computing balls (1), which also carry out wireless communication of data with one another. The computing balls (1) may be poured at random into a container (6), and intercommunicate to form a computing device.
