VW Polo 'singing dog' by DDB London.
Transport for London 'optical illusion' by M&C Saatchi

The singing dog totally rules. I've worked on that brief so I know it ain't easy; big props to the team. And just check the YouTube comments for proof of how much the public loves this ad.
The optical illusions one hits a completely different bone. Very clever. Very thought-provoking. I love the fact that they show a car crash without showing a car crash.
P.S. Now that we're seeing everything first on YouTube and not TV, an interesting test of an ad is "after watching it, do you immediately watch it again?"
I went 'yes yes no' on these 3. What about you?
