a) providing a mould (10),
b) introducing a number of piles (11, 12 and 13) of a cementitious mix into the mould (10),
c) vibrating the mould (10) for a limited period such that the piles (11, 12 and 13) remain separated,
d) introducing a coloured mix (14) into the spaces between the piles (11, 12 and 13), and
e) effecting further vibration of the mould (10) to cause further flattening of the piles (11, 12 and 13).
