Using awesome-looking technology from Total Immersion that you may have seen on CNN – and wondered what the point was – Topps baseball card packs now come with special cards that can produce 3-D images when held up to a webcam.

Pop-em up and watch them roam around, on your card in your cam but in your physical world, doing basic things like pitching, hitting, and batting in a simple casual game world environment.

And if you missed it, Topps has a game you can play with your baseball cards (special versions thereof) called Topps Attax. Each player flips a card, and the one with the higher value wins.

Wow. I bet it took a lot of late-evening brainstormers to come up with that design.
