We bring you our highlights from this week’s digital travels.

Up in the air

You’d think having one airplane-turned-home would be enough, but Oregon-based Bruce Campbell, who’s been living in a refurbished Boeing 727 since 2004, wants a second – this time in Japan. The electrical engineer spends half the year in the city of Miyazaki and is looking for a decommissioned Boeing 747 to call his home away from home. Oregon Live has more.

Inside one of the world’s largest river caves

Laos may be better known for its mountains and tropical forests, but there are sights to behold in some of its deeper, darker corners too. Tham Khoun Xe is a four-mile-long river cave that few people have seen because of its sheer remoteness. Photographer Ryan Deboodt, though, has made the trip and documented the enormous caves for our benefit. Pry into Tham Khoun Xe via The Smithsonian’s magazine.

A vertical Central Park?

After the rise of linear parks around the world, the next step is – naturally – the mile-high vertical park. Design firm Carlo Ratti Associati has created a conceptual design for a green-covered tower, topped off with a public observation deck. ‘Imagine you take New York’s Central Park, turn it vertical, roll it and twirl it,’ the studio’s founder Carlo Ratti told designboom.

The kalaeidoscopic ceilings of Iranian mosques

Follow Instagramer @m1rasoulifard for a kaleidoscopic tour of Iran’s places of worship and their intricate mosaic ceilings. As seen on Fubiz, Mehrdad’s photographs are as much a lesson in the country’s architectural history as they are a visual feast of colours and patterns.

Moving house, the drastic way

Last year, American painter Ryan Mendoza took down an abandoned Detroit home, only to reconstruct the house in Rotterdam – all in the name of art and public service. The artist explains his thought process behind the unconventional relocation in a piece for The Guardian.
