On Friday 25th Februari 2011 on 20:15 GMT+1 an infiltration of the White House and The Pentagon took place, orchestrated from a temporary command centre installed at Club Karlsson in Amsterdam. Since then, two virtual (AR) Twitter balloons have been positioned inside the Oval Offica and inside the Pentagon press room. The balloons can be seen 'for real' inside these two locations, but elsewhere in the world, an 'artist impression' can be viewed. To view the, download the (free) Layar app for iPhone or Android and open layar "INFILTRAR". The balloon displays the latest tweet containing either the hashtag '#pentagonchat' or '#ovalofficechat'.
