Multimirror

The multimirror  is a square tunnel of elongated mirrors that are joined at their long  sides, similar to a kaleidoscope, but with four rather than three mirrors inside. The effect is, that an object  placed at one end of the tunnel, when observed from the other end, is reflected repeatedly in four directions.
Reproducing this feature digitally on a computer, leads to the emergence of totally unexpected and beautiful  patterns. Such patterns resulting from 49 times the same image, can be printed as multimirror graphs. Four examples related to Venice are submitted here.
