Electrical towers are often seen as eyesores. In Buenos Aires, the artist collective Doma turned the concept on its head, transforming one tower into a robot-like sculpture. The 45metre Coloso (‘colossus’) was the group’s official entry at Tecnópolis 2012 – a popular art, technology, and science fair. At night, he comes alive in neon colours, complete with an animated face and a beating heart. Thanks to a sophisticated lighting system, Coloso exhibits a range of moods: sometimes he winks and his heart seems to grow; other times his smile is practically demonic. The 2012 version of Tecnópolis came and went, but Coloso remains a whimsical fixture on the scene, towering over the crowds during frequent art, music, and food festivals that take place on the grounds. Tecnópolis is in the suburb of Vicente Lopez; frequent trains run from Buenos Aires’s Retiro station.
