Chain

The animated short Chain is about the ferocity and the clever adaptations of predators and prey in the natural world. A cute cicada chomps down on a tiny worm until he's confronted with a praying mantis, obviously an orchid mantis in this case. But then comes a peacock spider who'd love to eat them both. This simple scenario even has a dream sequence. The viewer doesn't know who to root for in this standoff because they're all emotionally expressive, but then again they are all bugs. 

Chain has won an awful lot of film festival awards. (via Nag on the Lake)
