Four distinct 4×4 geomagic squares occupy the corners of this picture, one yellow, one blue, one orange and one brown. Every square is both nasik and most perfect. The set of 16 pieces used is the same in each case. They comprise 8 complementary pairs. At the centre, slightly enlarged copies of these four squares (minus targets) are shown superimposed, their pieces now revealed as exactly coinciding with each other so as to pave the 16 four-coloured cross-shapes. Similarly shaped targets surround this ensemble.
