greyworld

We often delight in the simple pleasure of picking up a stick and running it along a set of railings, making a lovely “clack-clack-clack” sound.

greyworld tuned these railings so that when you ran a stick along them they played “The Girl from Ipanema.”

Created without permissions in cities around Europe, many versions have dissapeared. But some still remain.

To find them, all you need is a stick.
