Always impressed when companies go the extra mile. They didn't HAVE to send this fancy shmancy Cheesecake, but they did. 

Big shout to our developers at OneDesignCompany!

My favorites:

• BMW checkmate 
• Rubber ducky: though I wonder how effective it is because I don't know what it's selling. Hm...
• Urinal soccer goal 
• Homeless man: "Before you turn away, put yourself in my place" 
• McDonald's coffee & their large marketing budget
• Barbell in train
• Bounty ice cream

I'm most impressed by the interactive marketing shots.
