As someone who did belly casts of both my pregnancies, I still think most of those belly casts are beyond tacky. I like the idea of fiberglassing the cast, but bondage belly cast? Candy wrapper cast? Camouflage skanky tshirt cast? Tacky.
Rachel Toor has a book coming out soon called "Personal Record: A Love Affair with Running" about both ultramarathons, and ride and tie races, which are insane. Ride and Tie would be a good neatorama article actually.
