While I searched for something completely differen (a heart-warming 3-minute-long love story about a boy and a girl who meet each other at a train station every day), I found this instead:

The House near the Bus Stop

But beware, it's really scary!

Nice entry!

And while I was on Vimeo, I found something else that I think is interesting:

Good Grief, "a short stop motion animated documentary that explores the lessons we learn from dealing with grief and loss. Five real people share their true stories of losing something precious and what it has taught them about living".

I really like this thread so I wanted to share some more videos not for additional entries but just for contributing to the catalog of the cool claymation videos so far. I don't think any mention of claymation would be complete without the hilarious MTV Celebrity Deathmatch series so here are a couple of my favorites :)

Celebrity Deathmatch - Arnold Schwarzenegger vs. Sylvester Stallone:

Celebrity Deathmatch Robert Deniro vs Al Pacino:

Funny, those pieces of cheese actually look more like slices of Italian "panettone" to me...
The moment when the janitor swallows a whole cow is crazy!

Curiously, no one has mentioned GOG's "The Swapper" so far.

Damn, you are right. I even have The Swapper on my shelf, but never realized that it is claymation. I should really play it soon.

Not really claymation, but something clay-related from the Muppet Show:

Mummenschanz

Just looking at The Swapper I also wasn't aware that it was claymation, I only read about it later on and was truly amazed as it looks great. :)

Here's another wonderful claymation series for children. My godchildren loved it:

Pingu

There's also an educational Pingu game. Maybe we should vote for it on the wishlist.

Not in, but I love claymation! Wallace and grommit were a favorite for my siblings and me.

My brother and I watched this one a lot when were were young. It's called Prometheus and Bob. About an alien trying to teach a caveman modern things. Plus, there is an evil monkey!

This one is titled "Toilet". Enjoy. https://www.youtube.com/watch?v=x7cwWoK0gz4

In with Wallace and Gromit: http://goo.gl/61js8b :-)

I'm in!

WALLACE & GROMIT are fantastic movies, I truly love them - but I also sort of think that their perfect craftmanship makes their claymation less interesting than more rough animation where the clay figures actually look like clay figures, with fingerprints and everything.

The horror antology THE ABC OF DEATH (2012) introduced a fresh concept: 26 horror shorts based on the letters of the alphabet! I enjoyed that antology, it was a breath of fresh air, even if a lot of the entries were crap. The entry T IS FOR TOILET is done in claymation, in a really rough style:

Take a look at the fameous claymation scene from EVIL DEAD (1982) This really work along with the strengths of the clay:

HAPPINESS OF THE KATAKURIS (2001) is a grotesque horror-musical-comedy by master director Takashi Miike. While the movie is live action, its intro and the ending special effect are done in claymation. The movie is about a family who has bough a guest house. The problem is that 1) they have almost no costumers 2) the costumers they do have tends to die in wierd accidents. Here is the intro - if I have to pick one fave, this is it:

The king of stop-motion avantgarde is most likely Svankmajer, but he is not constrained to claymation.

I'm a bit of a fan of Aardmans claymation-sitcom REX THE RUNT:

Not in but thanks for the giveaway!

Found some videos by Allison Schulnik today and think that they are pretty amazing:

Forest
Mound
Eager

Not in, but thanks for your generosity, PaterAlf!

I'm IN!
I love Wallace & Gromit, but since they removed it from GOG I won't have the chance to play it. I don't believe that it will come back to GOG, so I'm definitely IN!

As for claymation videos, I would remind you about a film in 2000, called:
Chicken Run

Thanks for the giveaway! +1
