Words such as "complex" and "colorful" come to mind when I see Huichol beaded art. It is folk art of the highest quality.
If you haven't heard of the Huichol, a brief history is in order. These indigenous people of Mexico, maintained their tribal culture in spite of the attempted incursions of the Spaniards and Christianity.
All of their art forms represent their religious relationship with nature. Beaded art is part of their cultural expression. (Below are images of beaded animals, masks, prayer bowl and even a VW. Click to enlarge.)
