If you're giving a CD or a DVD as a Christmas present, here's a nifty trick you can do to make the gift wrap just as interesting as the actual gift. Sent in by Neatorama reader Philip Chapman-Bell, who wrote:
This is the instructables.com tutorial for the Spiral Data Tato, a curiously complex origami CD or DVD case that can be made from one sheet of A4 or Americadian letter paper. The paper is folded into two double helices and zipped up with a single helix along the rim. It makes a delightful zipping sound when opened (see the ten second video in step 8). The perfect thing for a mix CD or a Christmas present for the unattainable beauty in your Calculus section.
