Contemporary Japanese artist Chiho Aoshima has brought a distinct ambience to London's otherwise gloomy subway with her first major public art commission in Britain, titled "City Glow, Mountain Whisper."

The artwork -- spread over 17 of Gloucester Road Station's underground arches -- features a fantasy landscape of faces, which gradually transforms from day to night and from a rural to urban scene in an echo of the daily journeys of subway passengers.

Aoshima's distinctive work, created digitally and printed onto vinyl, is part of a wider "Platform for Art" program initiated by the London Underground.
