From the YouTube description:
A very rare and clever toy produced in Germany approximately 1885 until about 1905. The little hand-cranked tin artist draws with a graphite stick onto paper via 'programmed' double-cams (x and y axis).
Some texts say it was an expensive wealthy person's toy, and other texts mention it as a give-away to favorite clients of the firm Phillip Vielmetter Mechanische Werkstatten of Berlin, Germany. This ultra-rare original box was repaired by Randy's Toy Shop.
I suspect the 5 cams are from various production dates. They are labeled (in German): HAHN, KAKADU, GLADSTONE, HARLEKIN, AFFE. There are several more cams that I do not have, such as Napolean, Balzaax, Queen Victoria, and still others.
I had only seen photographs of this amazing toy in the books Mechanical Toys (Spilhaus and Spilhaus)and Automata and Mechanical Toys (Hiller). It's great to finally see the actual toy in operation! Now...to get a peek inside...
