The surface of each of a series of interlocking paving blocks 1 is patterned in relief in a geometrical manner based at least in part on the geometrical configuration (28) of the block. The patterning x may take the form of shallow grooves centred on parts of the geometrical configuration. Alternatively, the surface may have one or more raised areas separated by extensions of the geometrical configuration. In this manner, the visual appearance of an area paved with the blocks is not determined solely by the joints between adjacent blocks. <IMAGE> |
