I've seen this short on "Czech Animation Master", and it's too bad that no one has already comment it... Hermina Tyrlova is a great experimentalist and innovating master of the stop-motion animation, above all if you consider the years when she worked.I'll comment the others too in my spare time; meanwhile take a look at this romantic story of two wool skeins, and realize the big input she could have given in the stop-motion art. Beware to consider it too outdated: maybe nowadays no one would make a short like this, but they wouldn't even have nice ideas like this one. Reflect upon it, then you could watch other works from a different point of view.
