Typical art travels inside, safely stowed in carefully-packed containers to prevent damage – these drawings do the opposite, playing up the folk-artsy practice of scribbling into built-up grime on vehicles.

“Using his finger to scribe into the layer of dirt built-up from exhaust emissions,” Ben Long “creates elaborate drawings on the rear shutters of white haulage trucks. In this on-going series, collectively entitled The Great Travelling Art Exhibition, he expands upon the daubing and crude slogans that commonly adorn commercial freight vehicles.”

Some of the pieces will be rapidly wiped away by rain or vandals, but others have survived for as long as six months and on long cross-country road-trips made by their drivers. Like street art, these reverse graffiti works are susceptible to the elements and necessarily temporary.

The artist’s motivations are various, but include a desire to make his work more accessible outside of traditional gallery spaces, reduce the costs of creative expression by using free materials and obviating the need for a studio space in which to create.

At the same time, there are a lot of artistic conventions still in play here – hallmarks of the ‘high art’ world, as it were. Long crafts these compositions within (and with reference to) a fixed frame, much like a canvass, and signs the pieces as well.

Nemo and his companions on the Nautilus would find themselves quite at home in this self-contained underwater retreat, complete with wraparound views and dubbed Lovers Deep.

A project of Oliver’s Travels, the vessel can help the rich and famous sneak away from prying eyes, submerging itself then depositing its passengers on a remote romantic island, or simply treating its hidden guests to secret seafood dinners under the sea.

The interior features a full kitchen, bar and living spaces with long horizontal windows to take in the scenery and wildlife. Chefs and concierges, located on the upper level but available on demand, can be provided as well to help customize the experience.

However, unless you, like the eccentric protagonist of 20,000 Leagues Under the Sea, can offset the cost of your voyage via hidden stashes of wealth, you may have a hard time paying the $100,000+ per-night price tag this vessel demands.

In this strange circus performance piece, two travelers turn architectural conventions on end, moving an offbeat nomadic home through a comedic narrative via carefully choreographic actions. A bit of theater-to-go, The Wheelhouse features careworn gypsies, and revolves around homeless living but is bolstered by conceptual architecture and compelling acrobatics.

Per the video above and images below, this quite dynamic acting duo from the Acrojou Circus Theatre have taken their show quite literally on the road – audience members have to walk or ride alongside their curious portable stage, consisting of domestic essentials packed into a portable circle.

Doors, windows, furnishings and fixtures are all affixed to the inside of this unbalanced blend of off-kilter architecture and vertigo-inducing set design. Their half-hour performance consists of walking, sitting and laying down inside the circular structure as it winds its way down streets and sidewalks.

A hidden sound system provides the soundtrack for the piece, and the set itself can be deconstructed into three pieces – that bit is perhaps too bad: it would be neat were the rolling architecture a part of their traveling circus caravan.
