M&M's Dark
Even though Ad-Rag has pointed out this idea has been done the death lately, the M&M's Dark Movie hunt game is still really fun. You can even download the image at full res here.
It's always fun keeping track of the trends. We had Subservient Chicken, Then Trailer Crashers, 'aveaword and now this as idea thats are copied until peopel get sick of them. The annoying part is the ideas are too tempting to fall back on when brainstorming.
One nice adaption of the idea is this promotion for Viking Direct called Stationary Movies. It's a great way to make office stationary fun and for what seems like a boring client, it's quite a fresh idea. It's also gone one step further than the other brands by allowing peopel to submit their own Stationary movies.
