London design studio Troika have recently installed this superb kinetic sign directing visitors to London's V&A Museum from the tunnel at South Kensington tube station.

Called 'Palindrome' the piece is a revolving version of Alan Fletcher's V&A monogram, suspended in a cylindrical ceiling-mounted capsule.

According to Troika "the logo decontructs and reconnects itself with each half turn forming a playful palindrome legible from either side, while the wheels produce a gentle ticking sound reminiscent of a Victorian automaton clockwork."

Made up of some eighty-five handmade elements (including fasteners, gears and a housing case) the whole contraption evokes the objects and the ways that they're displayed in the Victoria & Albert museum itself.
