I found this using Stumble. It’s a fun (though bizarre) animated short by Pascal Campion about a man trying to open a very unique cartoon door. It appears to have been done in Flash. The timing is sharp, the animation is fluid, and the concept is delightfully simple. There is no sound or dialogue, just pantomime done very effectively. It runs a bit long, but you can tell the animator had a ton of fun doing it.
This little cartoon highlights one one of the often overlooked strengths of animation: the ability to really mess with physics, time, and space. This piece reminds me a bit of the work of Bill Plympton or “Duck Amuck” by Chuck Jones.
