i fail to see anything surprising here. look at the black border... at no point does either configuration make an actual sqaure. the peices aren't the size they appear to be due to the optical illusion created by the uneven angles of the cut (and slight curvature of the sides) of each piece in relation to the piece next to it. rotating them alters that illusion thus changing the apparent shape of the piece.

I can't believe that people are saying the answer is in the outside lines, or "stop motion"... I also can`t believe people don`t remember this stuff from high school geometry class. (over 10 years for me, and I remember it... and I was the biggest pothead in my school)
Allow me to REPOST my earlier explanation.
The white square is evidence that the entire square is imperfect, so that when the pieces are cut at angles and rearranged, the imbalance in the sides of the square are evident as "negative space" in the final result...
The right side of the square is slightly shorter than the left side, and the top is slightly shorter than the bottom. This difference could add up to a mere 1 sq cm, which is hard to really notice when looking at the larger picture, but when the pieces are cut and rearranged, the 1 sq cm is what is left in the center...
Didn`t anyone ever watch Mr Wizard? I seem to remember him doing an example of this in a
