A lot of the body modification pages I’ve been finding through stumbles are mostly ads, but Body Art from the Australian Museum is a really high-quality site. It’s well-designed and attractive, and includes features on body painting, piercing, scarification, tattoos, and shaping (corsetry, footbinding, headbinding, and cosmetic surgery). Each section includes a basic history, pictures, and quotes from practitioners, and none of the pictures are particularly explicit or shocking. It’s definitely a good overview of body modification in general.
