turn yourself into a creepy old man

Or a pumpkin. Or a gorilla. Or a robot alien dude. Meijer just launched this halloween promo that uses your webcam to add a virtual mask to your face, and then lets you record a ransom fun video to send to your friends.

I like how they integrated product into the campaign, allowing users to browse and buy Meijer Halloween product right from the interface. So many retailers overlook that option when creating promotional campaigns, and miss the opportunity to sell.
