You’ll need some red/cyan (anaglyph) 3-D glasses to view this page.
Look for “red and cyan 3-D glasses” online. They should look like the ones at the bottom of this page. Amazon has some great deals on 3-D glasses with cardboard frames.
You’ll use the same glasses to view the 3-D section of our book, Prodigal Pig Tale, available in both Kindle and iBooks editions.
