BioDigital is a website with applications for iOS and Chrome that provides interactive digital models to businesses and educators. The U.S. National Library of Medicine also provides complete, three-dimensional models at its website for the Visible Human Project. Another option, aimed at children, is the Visible Man model kit.
BioDigital's three-dimensional models of human anatomy are used in a number of educational applications, including training for surgeons. The site and its mobile apps are free, but it does provide paid plans to schools and businesses that intend to use its technology in lesson plans or medical training. The National Library of Medicine's Visible Human Project, on the other hand, is completely free and offers real anatomical photos of fully dissected human cadavers. Finally, Visible Man model kits are a popular project for scientifically oriented children. They are available at a number of toy and hobby stores, including Discover This, a leading educational toy website.
