Sheer Madness

A very hard logic and packing puzzle in one. The puzzle contains 2 matching sets of 16 pieces? a white set arranged in a 4×4 grid, and a red set of identical shapes which can be manipulated so as to create composite shapes. The goal is to rearrange the 16 white pieces within their 4×4 grid so that the red pieces corresponding to the 4 white pieces forming any row, column or either diagonal are then able to tile a 5×5 square and fit in one of the frames.
