The “First Kiss” video gets me every time. It doesn’t matter that, in addition to being the first kiss among two strangers, it is also a very very clever ad for a clothing company Wren. The video has gotten a considerable traction on YouTube (79 million views and counting).
Despite some negative reactions ("this is advertising!!"), I really love both the idea and its execution. In the age when invisible technology is all the rage, why should invisible advertising be looked down upon?
