The look I think you're referring to is called Cel Shading, it's computer animation used to mimic conventional animation. It's been used mostly in Japan for shows like Zoids and the latest Gundam series, Gundam Seed; it's inexpensive and sharp-looking, but used mostly in shows that are actually toy commercials. It's appropriate here, I guess, seeing as how these shorts are really three minute toy commercials. No, not that 3-D, I don't think it's Cel Shading, but I'm no expert on the subject. It's not 3D a la Toy Story and stuff like that, just a bit more 3D than Jack (because that's 2D) You'll see what I mean if someone can get the preview up.
