I'm halfway certain that there is sorcery from Middle Earth involved in building this humungous chain. But it's pure human ingenuity. The chain is meant to be used on Shell's Prelude project (a floating liquefied natural gas platform) which is basically some ginormous platform that's permanently moored offshore.
Take the Pixar Luxo Jr Lamp and then remix it with a recycled bicycle chain and what do you get? An incredibly cute lookalike lamp that can be bent and shaped in multiple directions.
