As you may be able to tell from my last few posts, lately I have had a bit of an unhealthy obsession with puzzles. These two both concern things that go missing, or appear, depending on your perspective. Please leave your thoughts on these two puzzles in the comments.
In the first, count how many men there are in the animated image. There should be 12. When the top halves of the men switch, count again. There should now be 13. Where does the extra man come from and where does he go?
In the second, when a series of shapes is rearranged, 1 square is missing. How is this possible?
