I'm looking for information on printed animation. What I'm talking about is like a baseball card that changes it's picture depending on the angle you're looking from. So, say it's a picture of a batter, as you turn the card you'll see the guy swing the bat. I know I've seen this stuff before in other non-baseball card media but I can't remember any other examples off the top of my head.
If anyone knows what I'm talking about, I'm looking for how exactly it works, what it's called and possibly who can print it. Any help would be greatly appreciated.
Thanks in advance,
