A 85 ton sliding glass door covers a large building in Paris. It is metres from the Seine! It opens and closes two times a day. (I will shoot video soon, and add it)! Its a very cool building. Go look at the gate! And, then ask tyourself "why"?! <br /><br />There are dozens of these videos, many little known, insolite et cache histories de Paris at: <br />http://www.youtube.com/user/60seondparis <br /><br />I just joined and will be posting french version in the near future! <br /><br />merci! <br />David
