Product-tested by a husband-and-wife team of architects in their own abode, ‘A Cat Thing‘ was developed to let pet owners construct an endless array of feline crawling, hiding and resting spaces for their furry friends.

The design consists of four modules — room, living room, balcony and ramp — that can be endlessly stacked, joined and rearranged to make new buildings.

The prefab modules can also be packed flat for shipping and storage, then deployed on demand. The use of recyclable cardboard makes them light and easy to assemble, and non-toxic (safe for feline occupation). Inspired by origami, the system requires no special connectors or tools to construct mega-structures.

The design duo started experimenting with help from their own cats, Chacha and Lily, seeing how they responded to different units and configurations. And as any cat-lover knows: this species seems to love boxes.

“The relationship with cats is a mutual one, so the design for ‘room collection’ should be adjusted to the behavior of the felines. in the future, ‘A Cat Thing’ aims to redefine the products we use with our pets daily,” say the designers, who are “looking forward to bringing more style, attitude, quality and sustainability” to future designs.

This series of recycled cardboard models references both the functional styles of postwar Soviet architecture as well as the Russian tradition of handcrafted nesting dolls.

In the wake of World War II, European cities were forced to rebuild in a hurry, focusing on cheap and efficient structures that could effectively be mass-produced. Blokoshka (from: Matryoshka and blocks) by Polish studio Zupagrafika borrows from the pragmatic minimalism of this architectural history.

The four units represent four types of building in four places:  the sleeping districts of Moscow, Plattenbau Constructions of East Berlin, ruin-topping estates of Warsaw of moscow, and Panelak blocks of Prague.

The prefabricated pieces are nestled in sheets of cardboard, ready to be folded into place without the need for glue, scissors or other tools. Each resulting structure tucks neatly into the next, so the sets can be deployed into districts or recombined into shelf-sitting modules.

If you can build a foosball table, a desk or an entire full-scale chapel out of cardboard, perhaps it’s not too surprising that this notoriously flimsy material can form the basis of a working Fender Stratocaster guitar. Signal Snowboards previously teamed up with Ernest Packaging to create a corrugated cardboard surfboard, and now they’ve built a custom Strat that even impressed the expert guitar techs at Fender.

The way the cardboard is assembled and shaped makes it surprisingly structurally sound, which is a good thing considering the strings put about 250 pounds of torque on the neck of the guitar. Once it was all glued together, Signal took it to Fender and had their techs cut it into shape and add three 50s single coil pickups, a Stat scratch plate and other Fender components. When held up to light, the body and neck of the corrugated Fender is nearly see-through.

Automobile owners in Amsterdam are waking up to find that their cars have been ‘customized’ overnight with cardboard and masking tape. Suddenly, their boring old sedans boast body fenders, spoilers, grilles and hood scoops. You’re welcome, says artist Max Sidentopf, creator of the ‘Slapdash Supercars’ project. Maybe the new additions won’t even survive a quick trip down the street, but that’s not really the point.

“Individuality, self-expression, and status are more important than ever these days,” Sidentopf tells Vice. “But for some reason you see that things as ordinary as cars are getting personalized less and less, while it could be a strange but great form of self-expression. I thought I’d do people a favor by giving them a custom-made supercar.”

The result is undeniably goofy, and the reaction of the owner is probably a test of both their sense of humor and how precious they are about their vehicles, since not everybody is crazy about the idea of strangers clambering all over their cars and leaving tape residue behind after the customizations have been removed.

It’s a simple prank, and a funny way to remind people of the creative possibilities in each day, whether you have any desire to actually pimp your ride or not.

This holiday season brings fresh printer-compatible designs of low-poly skeletons, monsters, animals and more for the do-it-yourself costumer, all scaled to fit an adult or resizable for children.

Like a polygon mesh in 3D computer graphics (that has a relatively small number of polygons), these masks are leant a haunting effect unique to the digital age, looking otherworldly and surreal like low-resolution computer renderings.

Some models are more complex than others, involving sets of articulated parts that rotate on simple hinges or pivots, like the tail of a fish, trunk of an elephant or the hands of a dragon.

The key ingredients: a printer, some paper of applicable color, glue sticks, craft knife, tape, cardboard and an elastic headband. If you have more time than money, or simply enjoy the process, these models provide a great balance of personal work and creativity within a ready-made outline.

From their maker, Wintercroft on Etsy, who sells the plans online:  “The instructions and templates are designed to be quick and easy to follow. The finished masks are pretty robust due the their polygon construction and will survive the wildest of parties.

More on Steven Wintercroft: “By nature I am obsessively creative and starting making things as a kid with my granddad. I studied Art and design, then furniture studies and have been designing and building custom surfboards since I was a teenager. I’ve worked as a cabinet maker but have spent most of my time as a full time surfboard shaper. I believe that the urge to create is a fundamental part of being human and these masks provide an excuse to sit down, get out the scissors, tape and paint and make something” (via Colossal).
