Netherlands Debuts Video Stamp

Lenticular Stamp1Gizmodo has a story about a "video" stamp issues by The Netherlands. The stamp uses a technology called lenticular printing. The printing company web site describes the the process:

The material is made up of tiny ridges or lenses (hence the name “lenticular” printing). We take raw images and process them through a computer algorithm, which matches the lens surface of the lenticular material. When the two work together it enables the image to be replayed back to you.

I saw some examples of this week at school. Several students gave away Valentine cards that utilized this technology. Kind of reminds me of the animated newspapers in the Harry Potter movies...
