It’s a tale as old as time, or at least: science fiction films — an autonomous grocery store on wheels (staffed by a holographic assistant) that can deliver late-night snacks as well as everyday essentials.

The Wheelys “Moby Mart” looks the part as well, sporting a trapezoidal shape, illuminated display in front, vintage neon sign on top, and mysteriously uniform boxes on the shelves inside.

But that retrofuturistic look is just part of the package: fueled by solar panels on the roof, this driverless shopping center operates staff-free 24/7.

When it runs low on stock it returns itself to a warehouse automatically for reloading — eventually, its makers hope to task a fleet of rooftop drones to do those pickups (maybe they could be extended to make deliveries, too).

Like other new grocery store prototypes, there will be no need to check out — items taken are automatically tallied and added to a shopper’s bill. If you need any help, the aptly named Hol (a holographic store assistant) is on hand to assist.

To top it all off, the Moby Mart has the potential to be carbon-negative, at least in terms of its urban travels — soaking up the sun for fuel, it also captures and cleans smog on its grocery runs.

A project of Himalayafy, Hefei University and Wheelys the first prototype is currently being tested out in Shanghai, a sweet spot for cyberpunk fans but a bit far for some of us to travel. But don’t worry: if all goes well your city may get one soon, too.

In a remarkable 24-hour collaboration, a series of artists banded together to build a replica of the infamous house from the Wizard of OZ – that ill-fated structure that carried Dorothy Gale so far from Kansas.

This fast-paced process employed by the Resisting Entropy team was intentional, designed both to show what dedicated teamwork can accomplish in a limited amount of time but also meant to emulate the chaotic conditions of a wild twister.

No Place Like Home was hosted by the owner of Asymmetric Arts in Rockland Maine, Jared Cowan (special thanks to contributing artist Eric Leppanen for the tip – full list of artists below).

Also part of the plan: the installation was created piecemeal, then put together into intermediate sections before being transported to the site and assembled as a whole.

Starting with a previously-gathered scrap pile, each artist drew what they needed along the way, imbuing the separate sections with individual twists and quirks.

In the past, Resisting Entropy has brought together artists to create a series of independent works, but No Place Like Home gave them a curious and novel combination of individual liberty and a cohesive goal.

Contributing artists included: Jared Cowan, Andy White, Bethany Engstrom, David Allen, Eric Leppanen, Trelawney O’Brien, Alexis Iammarino, Siglinde Langholz, Owen Cartwright, Greta Van Campen, Susan Smith, Jonathan Laurence, Ashley Seelig, Sean Taylor and Kelsey Floyd. “Resisting Entropy is an exercise in creating collaboratively within a condensed timeframe and shared space. Participating artists are presented with a large volume of discarded materials and over 24 hours, live and work together to transform the volume into unique and unpredictable artworks.”

Despite the wind-strewn look, the structural design had to be carefully checked: “The base structure had to be strong enough to not fall due to a strong gust of wind.  No one is allowed in the building due to safety concerns but people can get close enough to look into the windows therefore some of the crew focused on structural integrity.  The design of the roof on the other hand had to be light and airy so that a crew of four or five could lift each section into place. Notice the skeleton of the roof structure, made with the thinnest boards possible.”
