Your mailboxes never looked so good! Spontaneous worked with MRM to launch a new holiday smartphone app for the U.S. Postal Service. These whimsical holiday animations come to life when the collection boxes are scanned. Over the course of the holiday season that familiar blue mailbox will sprout a fully decorated Christmas tree, transform into an igloo with a dancing penguin inside and don a festive red sweater. The result is a magical experience for the millions of USPS clients at one of the busiest times of the year.
