So were the chocolate pieces all directly 3d printed, cast from 3d printed molds, or what? Something about the shapes screams "made by a computer" to me.
I'm not sure, I couldn't find much about it besides the video. These kind of optical illusions have been around for ages though, so it's possible it's a very skilled artist or chocolatier, but it's very likely computer assisted in this day and age.
According to the description it's from a chocolate factory; I thought it was homemade when I posted that. If it's from a factory, I'd be shocked if it weren't completely fabricated.
Still very cool though, I've only seen slit zoetropes, doing it like this is way cooler.
