If you have 10 minutes to spare I strongly urge you to watch The Eagleman Stag, a lovely stop-motion short film by UK animator Mikey Please that won the 2011 BAFTA for best short animation. From Jason Sondhi’s review on Short of the Week:
Animated through stop-motion, the film incorporates thousands of hand-created models across 115 sets to tell the story of Peter Eagleman. From a young age, Peter possessed a peculiar awareness of time. Obsessed with the concept that any unit of time represents a differing fraction of one’s life depending on age, he becomes preoccupied with this “speeding up” of time as he grows older, and longs to reverse the process. In the meantime Peter grows, lives, ages. He becomes a celebrated entomologist, and through his work he stunningly stumbles upon a possible solution to his lifetime’s angst.
The foam used to create the models has such strange properties it’s difficult to believe these scenes aren’t digitally rendered. You can see a few making-of shots here. (thnx, jason!)
