HP Flip Magic! photo paper

I bought this kit ages ago, in 2003, and it's amazing they stopped selling it. I was looking for something like that last month, and the closest I could find was http://www.thinkgeek.com/homeoffice/gear/9781/.
It's a complete kit to make your own lenticular photos, those that switch between 2 images when you tilt them. It contains photo paper, lenses and software. The images displayed are too far apart to use for 3D, though.
With the new craze in 3D, they'll probably bring this back soon.
