Many years ago I downloaded photos of guys exploring tunnels filled with deep, creamy light colored mud wearing jeans, sneakers, boots - I think they were in Paris. It was called ProjetX (yes that is the correct spelling).

Some of the photos had guys laying on their back in the mud beating off. The photos had the tag "mercury@projetx.com" printed on them. The web site is long gone.

Due to a computer change I lost about half of those photos. Does anyone remember that group and have a cache of their photos?
