One of
the recent Halloween night's parties contained a puzzle which is
presented here.
The puzzle consists of eight pairs of pieces - 16 in total, which are scattered around the 4x4 square
above. Each
piece in a pair moves around some imaginary center relatively
one to each other as shown in diagrams at the left. At the same time
the pieces in a pair can be rotated at 90 degrees in clockwise
direction. When a piece in a pair is rotated the other piece in
that pair is
rotated too - just as shown in the diagram at the right.
The objective of the puzzle is to arrange all the eight pairs
within the 4x4 square above so that some image appear.
Move the pieces dragging them, rotate the pieces clicking them.
It is enough to drag one of the two pieces in a pair in order
that another piece is moving too. And also it is enough to
click one of the two pieces in a pair to rotate both of them
simultaneously.
Each time you want to begin the Rotation Movin' Party again -
simply click the Restart button and it will scatter back the
pieces around the the 4x4 square in random order.
