This is definitely a weird one, but (in a way) for both our meat eater and vegetarian readers. A house made of meat sounds horrible, but what if it was a victimless structure? What if the meat used to construct the house was grown in vitro, in a lab? Okay, yes, it's still somewhat horrible. But not nearly as horrible as the idea of using sphincter muscles that can open and close for windows and doors. How do you get it to open? Just a little tickle near the edge, obviously.
