Guinness lightens up with light-show spot

We’d hate to see the electric bill for this building after they shot this Guinness ad, in which a band of pranksters flick the lights on and off by floor to emulate the “soft pour into a pint” technique made famous by the legendary dry stout. This impressive visual effort was intended to “entertain, engage emotionally and capture people’s imagination,” says a rep from Irish International BBDO in Dublin, which made the ad. Not sure if that’s how it was received, but that’s exactly what Guinness does to people who drink too much of it.
