This is a picture of a public toilet in Houston...
and now that you have seen the outside of it...
let's look at the inside...

...it's made entirely of one-side glass...
no one can see you from the outside...
but you sure can see them on the inside!

Ok, now picture this,
you are at a party...
in a penthouse...
then you need to go to the washroom...
and you step into this...

ok, so this is only painted on...but still,
would you dare walk into it...
would it mess up your mind?

Last, this is a ceiling mural in a smokers' lounge...haha.
