I live down the street an work in the same building as the apple hq in Sydney Australia and right now the office is flooded with colored shirts. I asked one of them what it was all about, dumbly pretending I knew nothing of tomorrow and was told it was for "product training".
Sadly there is a strongly enforced no pictures policy in the building BUT it appears as though the employees are updating Foursquare freely
