Something different: Timelapse video - making pierogi

I have something different for you this time - a video timelapse from my kitchen. My wife and I are Polish but we currently live in the US (Memphis, Tennessee).

We organized the Christmas dinner with a couple of Polish friends here in Memphis, everyone cooking something.

There are many traditional Polish Christmas dishes, one of them are pierogi (dumplings). My wife and I made so many of them (around 400!!!) that I had to record the process of making them, just for fun :) The result is this video:
