| | Paper Folding (Site not responding. Last check: 2007-10-03) |
 | | If a large sheet of paper is folded in half, then in half again, etc, with all the folds parallel, then opened up flat, there are a series of parallel creases, some pointing up and some down, dividing the paper into fractions of the original length. |
 | | From this view, the only unchanged part of the original paper is the piece containing the ``start edge'', and this piece will be horizontal, with the ``start edge'' on the left. |
 | | The end of the input will be marked by a line containing a zero. |
