I did this drawing for the nice people at the Zuiderpershuis in Antwerp. Featured on their website here. It's my pimped version of a technical drawing of the old hydraulic system.
The building used to be an energy plant, but is nowadays a cultural center.
The original image was a complicated black and white technical drawing and the quest was to do an update, to make it more fun for kids to learn about the workings of the machine.
