Some ideas..

Here's a nifty animation about one day in the life of a junior government agent

The film took nearly 5 years to complete and is the first attempt at animation by writer/director Lucas Martell.

There are a series of "how-to" podcasts presented for viewing after the main feature. If the link above fails, then simply search utube for "Pigeon Impossible."

Cheers
