I think you fold yourself and shove butt in first into opening.
no, think yourr getting confused with the Contorsion Toilet system.
If it is like I think it is... its a bucket the folds down.... you take care of business and when you fold it back into the wall it dumps the contents from the bucket into the tank below. Interesting concept.
been toying with designs of compost toilets where the user did not have to stare down a hole with nasty stuff below before and after use. This fold and dump concept might work for this too.
