I was so impressed with the high quality animation of Kiwi! that I continued to search for other short films on YouTube.  Here are some other films that I found that you will certainly enjoy:

Joe's Playtime was created by Kevan Shorey as his final project while in university.  With this short film, he won second place at the 2001 European Junior Animator Awards.

Genre: Drama

Plot: Joe defends himself and the planet Earth from the evil "V" and is sadly disappointed when his playtime is interrupted by his mother calling him for dinner.

Block Test is another short film by Kevan Shorey.  This short was made for his final Masters project in 2002.

Genre: Comedy

Plot:  A green block undergoes a screen test and is upset with the amateurish setup he has to work with.  Those of you who have seen Monsters, Inc. will notice several references to the movie.

The Cheese Trap was created by Dane Barney and Camden Davis as a first quarter final project for university.

Genre: Mouse and Cheese Chase

Plot: A couple of mice discover a clever way of catching a runaway piece of cheese by using the classic game Mouse Trap.

Here is another Mouse Trap short called The Hot Tub Trick created by Matt Titus and Joon as a final project.  (The assignment was to base their short film on the game Mouse Trap -- I'm guessing "The Cheese Trap" creators were in the same course.)

Genre: Suspense/Thriller

Plot: The creators were inspired by the fairy tale Hansel & Gretel for this short.  Two mice are lured into a trap and are threatened to be dinner.  Will these mice survive?  You'll have to watch to find out.  (Notice the Brazil theme song at the end.)
