The US Postal Service will turn 400 mailboxes into R2-D2 look-alikes as part of their plan to celebrate the 30 year anniversary of the release of Star Wars. The BBC reports that the droid mailboxes are "part of a post office campaign for the announcement of a surprise stamp on 28 March." The USPS say citizens are "urged not to tamper with the droid mail collectors." Could there really be any Star Wars fans who will want one of those 400 R2-D2 mailboxes for their very own enough to steal it? The USPS has put up a website about the event that will go live on March 28. More details and photos of an army of R2-D2 mailboxes can be found over at TheForce.Net
