Does anyone know how to make left-to-right mirror images of PDFs?
My daughter and I had fun today using Joel Hamkins' fold-punch-and-cut PDF ( http://jdh.hamkins.org/math-for-nine-year-olds-fold-punch-cut/), and I thought that this activity would be even better with double-sided pages in which the markings appeared on both sides; this would make it both easier and more pleasant to fold the paper accurately. A simple approach would be to create mirror images of the pages; printing an image and its mirror-image on opposite sides of each sheet would create exactly what I want.
This isn't an answer to your question, but: how well this works will depend on how accurately the printing on the two sides is aligned, and I wouldn't rely on that being terribly good. (But I haven't actually done the necessary experiments; maybe printers are really precise about this now?) -- g
