What artistic and/or functional household objects could you make with pieces of your own body?

Browsing my past posts, I was reminded of how I got startedon my current project:

Top that. And no cheating, you have to do it yourself and remain alive to admire your own work.

You could knit yourself a hair-shirt.

A battering ram.

I suppose that, if you collect your own excrement, shape it into oblongs and bake it until it’s hard enough, you might be able to build a house out of the “bricks”.

Not sure that I’d want to visit you, though. And I’m not sure that shit counts as “parts of your own body”.
