An artist has produced a fitting work to commemorate the 2012 Olympics - a mechanical sculpture of an athlete doing push-ups, made from a traditional London bus.
With two giant arms and an electrical engine , the 1957 bus has been transformed into a piece of art by Czech sculptor David Cerny.
The work, named London Boosted, has been installed outside the Czech Olympic House in Islington, north London, to mark the Games' opening in the capital on Friday.
Wiring and suspension tools help the six-tonne bus move up and down on bright red arms, raising the chassis into various angles, accompanied by recordings of a groaning voice and video projections in the windows.
Cerny, who bought the bus from an owner in the Netherlands, said: 'There is one common exercise for every sportsman in the world, and that is push-ups. 'It is training for sport activities but at the same time it is also punishment in armies and prisons. So the push-ups are a very universal physical activity... It is in a way very ironic.' The sculpture is less controversial than some of Cerny's previous works, which have enraged European politicians and sought to poke fun at rival artists.
In 2009, as the Czech Republic began its EU presidency, Cerny revealed a huge puzzle-like object called Entropa, which portrayed European countries in unflattering ways. The work, installed in an EU building in Brussels, attracted protests from Bulgaria, which was shown as a squat toilet.       –DM
Germany was a Swastika-like web of highways, including moving cars, France was covered by an 'On Strike' banner and Britain was missing altogether.
In the Czech Republic, Cerny once painted pink a Soviet tank, which was serving as a monument of the Allies' 1945 liberation of Prague from Nazi control.
His work Shark was a statue of former Iraqi President Saddam Hussein floating in formaldehyde. It was meant to poke fun at British artist Damien Hirst's embalmed shark, and was banned from exhibitions in Belgium and Poland.
In the 1990s Cerny also sparked controversy at an art fair by putting up large replicas of guns and posters in London, calling on people to observe a 'Day of Killing' to control population growth.
Cerny said of his latest work: 'We will see how long the athlete can work out for.
'Let's hope he will exercise for the full three weeks. He will be the biggest sportsman there.'
Cerny's sculpture isn't the first work of art produced for the Olympics to feature an old vehicle in an unlikely new position.
Earlier this month MailOnline featured artist Richard Wilson's unusual installation of a coach perched on the toof of the De La Warr Pavilion in Bexhill, East Sussex.
The work is inspired by the final scene of the film The Italian Job, which ends with a bus hanging precariously over the edge of a cliff.
Mr Wilson named the installation after Michael Caine's last line in the 1969 movie - 'Hang on a minute lads, I've got a great idea...' DM

Rollerman pulls off craziest stunt yet (F23g, F23gg, F23ggg, F23gggg)
A FRENCH daredevil mastered a mountain road featuring 99 hairpin turns on a custom-made roller suit with 31 wheels.
Jean-Yves Blondeau, 42, who calls himself Rollerman, completed the stunt on Tianmen Mountain in Zhangjiajie, in south China's Hunan province.
The suit, which he designed, features rollerblade-like wheels on the torso, back, and most of the major joints, allowing him to ride in a number of positions at speeds of up to 70mph.
Mr Blondeau sped down the 10.77 kilometre road in just 19 mins 34 sec - giving him an average speed of about 20mph, reports the Daily Mail.
Rolling part-way down the steep, tortuous mountain road, and part way down a specially installed metal track, he used his body to steer as he hurtled dangerously towards the finish.
He even felt confident enough to catch a little air from a jump set up near the bottom of the track, before crossing the finish line to exploding fireworks.
Mr Blondeau originally designed his roller suit as his graduation project at an industrial design school in Paris.
Since then, he has created 20 generations of the superhero-type outfit, ranging from basic kneepads with rollers to sophisticated full body armour like the one worn in the Tianmen Mountain stunt. WO
