Hi.
The short by Paul van Driessen is only 2 minutes long. In it, some environmental issue concerning fresh air seem to be the topic. The animations are simple. So is the storyline.
We see trees, fish, a bird and another creature huffing and puffing but not making it. The animations are almost without color, which differs from later animations like 3 misses, and the technique doesn't seem as refined (or as blurry, if you like) as later on in his career. However, it's nice to watch. And for 2 minutes you can't expect too much.
Enjoy.
