Spectacular. ITV took an underground tour of Paris with l’UX and the folks from Untergunther. They started in the sewer, went deeper into the quarries that provided the stones from which medieval Paris was built, and ended up–well, I’ll let you see yourself where they watched the sunrise from. [thanks for the tip, lazar!]
