Greenpeace has sparred with Shell before. From shutting down 74 gas stations through ugly law suits to prevent protests and an ultimately successful defence, the campaign over arctic oil drilling has already seen its fair share of heated clashes.
But Greenpeace's latest stunt, which took place at the Belgian Grand Prix, is note worthy as much for its comic timing as its confrontational nature.
Just watch the video below.
As the video explains, the automated banners were created with a simple DIY hack to some ordinary car antennas. They were snuck onto the circuit some two weeks before, and then activated as the winners took to the podium. The intervention was part of a series of protests, more of which can be seen below.
Here are a couple of screen grabs, in case this video gets taken down too. (Please excuse the crappy resolution.)
