Although this is not a 3D animation, I feel that it still covers the style and interesting ideas of animations which I want to research into. Like Toy Story, this short focuses on small toy army figures, and animates their actions and movement really well, with an interesting narrative and concept. As 3D animation you are almost doing a stop motion animation, but moving a model on a computer screen with controls rather than with your hands in real life.

As a stop motion piece, they have used some really interesting techniques to create the effects that they want. A really interesting video, even if it isn't 100% relevant to 3D animation.
