I believe the answer is:

mosaic

(Other definitions for mosaic that I've seen before include "Pattern made with coloured peices of stone" , "Design of little pieces" , "Small pieces fitted together" , "Decorative work of small hard pieces" , "Tessellated picture" .)

I've seen this clue in the Sydney Morning Herald.
