Check this out. What do you think it is? Nope it is not a modern day tardis. (If you don't know what a tardis is then there is little hope for you I am afraid. Click here to redeem yourself.)

It is in fact a toilet at the Tate Gallery in London. This is what it looks like from the outside. From the inside the view is completely different, see below.

You are not imagining things, it is completely transparent. Made of one-way mirrors, noone can see in but inside it is like you are going to the toilet with clear glass all the way around.

It is a bit too much for some people, they find their ability to conduct their business, so to speak, impossible with views of the comings and goings of the visitors to the Tate in full view.

The Green Man thinks it is in the category of "must try".

And whilst we are on the topic of toilets, here is one in South West Tasmania. It is in a wilderness area so you have to walk a couple of days to get to it. Accordingly the passing traffic is somewhat limited but not zero. Still they are a friendly bunch in Tasmania and always willing to stop for a chat, even to someone sitting on a toilet in the middle of nowhere.
