Very cool, and reminds me of a good, somewhat funny memory. In high school (this is over 30 years ago), I studied German for four years. My teacher, Mrs. Maria Schmid, was one of the best and most memorable teachers I've ever had (in 19 years of school, no less). She had been born in Germany, and although her family had immigrated to America when she was only four, she seemed to embody what we Americans regard as the German character. (Actually, my grandmother (RIP) was Pennsylvania Dutch, I've worked for a family-owned business run by a German family, lived next to a German family and dated a German girl, and I have to say, they all seemed to share a desire for orderliness.)
Anyway, Frau Schmid shared her classroom with another teacher who wasn't meticulous about making sure all the desks were lined up and the windows hades drawn to the same level. Before class began, during the four minutes we were allowed for travel between classes, she'd walk to the bank of windows and calmly set each window shade even with the lowest segment of the windows. When the bell rang for the start of class--and not a second sooner--she'd stand at the front-left corner of the left-most column of desks. That was the cue: she'd trained the first student in each column to align the front-left leg of his or her desk with a little "right angle" mark she had drawn on the floor in indelible ink. As soon as the first person in the first column aligned his or her desk, people behind him or her line their desks up. With a very slight smile of serenity on her face, Frau Schmid would then go to the next column of desks, and so on, until all of the desks were in neat rows. With the world in perfect order, or at least as much of it as she controlled, she'd open her copy of the textbook and start the class, always the same way, every time, with a gentle voice: "Also gut. Heute fangen wir an auf seite....." ("That's fine. Today we'll start on page...."--edited to correct my grammatical mistake in German)
When I saw the video on Festool's German web site, all I could think of was mankind's eternal struggle to turn chaos into order, and the peace of mind that Frau Schmid seemed to attain when she prevailed, however temporarily, in that struggle.
