This creation by Czech artist David Černý was located outside of the Czech Olympic House during the 2012 games. Černý turned a London bus into a machine that appears to be an athlete doing push-ups.
Černý bought the six-tonne bus in Holland and spent six months fitting it with robotic arms are powered by an engine.
The bus even makes noises similar to the ones you’d hear from someone working out. The six-ton bus is attached to two hydraulic arms. The “bus” can now be found outside the Agrofert Headquarters in Prague.
