flip book title page
 
The above image is the first page of a flip book originally handed out as a 260-page puzzle. In the original unsolved state, the flip book shows a pie being consumed by an erratically moving black dot representing a fly. Each page of the book is labeled with a five-digit number. To solve the puzzle, the flip book pages need to be reordered such that their five-digit labels form the first digits of the number pi. The first page of the flip book contains all 1295 (5 × 259) digits of pi needed to solve this puzzle. Once properly reordered, the flip book shows a dot spelling out the solution one letter at a time.
