Deliberately Concealed Garments Project | Clothing found hidden in buildings

Was browsing the web, and looking at a particular web hosting company for its hosting offerings. Wanted to see some examples of the sites it has hosted, so I clicked on the link for "Featured Site of the Day", and I got directed to the site above.

Why in the world would anyone be interested in garments hidden in buidling? Apparently there is a group of people who are interested enough to create a group and spend the money and effort to put up a website. One more reason for me to be confused about the world.
