Rovio has signed a deal with Formula One driver Heikki Kovalainen to spatter his helmet for the 2012 season with the Angry Birds logo and the red bird's features. Kovalainen, who drives for Caterham F1, is from the developer's home country of Finland, so is a natural fit for the company.

The Formula One season starts this weekend, with Sky's F1 HD channel opening its live broadcasts with the practice sessions in Melbourne tomorrow (Friday 16 March).

Kovalainen's helmet isn't the only example of late of Rovio branching out with its Angry Birds brand. Recently, the company announced it was working with a major theme park in Finland to create an entire section called Angry Birds Land.

Plus, on 22 March, the developer will release a true sequel to its hugely successful game in Angry Birds Space, where such things as gravitational pull are added to the pig-bashing format.

And then, of course, there are still plenty of examples of home-made and other related products and tomfoolery, including Angry Birds inspired cakes, plush toys, spoof movie trailers, board games and even a real world version of the game.
