Sorry, not for development of anything close to sighted perception in normal adults but more an example of how some degree of non sighted perception is practically achivable. Fwiw my eyes work pretty well and I rely on them for everything, but also learned how to not break my toes in the dark etc. The shower thing is of course trivial though. Presumably people that rely on hearing exclusivelly for spatially oriented perception have a whole lot more nuance and detail on which to comment.
