Otomi embroidery is named after the Otomi people who live in Mexico. They do a particular kind of embroidery where they use false satin stitch - although it looks more like herringbone stitch to me. They use this stitch to conserve resources. As you probably know, regular satin stitch swallows up a lot of embroidery thread! You can read a bit more about Otomi embroidery here.
Anne has blogged about how she encountered Otomi embroidery and her first experiment with it.
