Cladding a cement mixer in pixelated mirror squares, a French artist has created a giant glittering disco ball on wheels able to turn vacant lots and construction sites into instant party zones.

Benedetto Bufalino often adds fun to the mix when working with interactive and installation pieces (unusual sports courts and strange phone booth conversions), for instance, but rarely in quite such a dramatic way.

Parked for a time next to a building site in Lyon and given its own spotlight, the artist’s remixed mixer spins up and casts light in all directions. The idea driving the project is simple: bring together locals and passing pedestrians to mix and meet in the resulting rays.

Of course, it doesn’t hurt that the entire setup is mobile — for guerrilla party throwers, the mixer can set up shop then move if complaints mount or authorities arrive. Or it can simply cruise slowly down the street, making for a truly and permanently portable party.

Meanwhile, when not at work hosting parties, the vehicle can carry and pour concrete as usual — like many urban residents, it is a worker by day but a partier by night.

Somewhere between architecture, art and fashion, this series of 3D-printed shoes by five famous designers for United Nude pushes the limits of new technologies to make fresh forms of fancy footwear. Not meant to be everyday apparel, these unique party-oriented accessories were created for Milan Design Week 2015.

Rem Koolhaas invited architects Zaha Hadid, Ben van Berkel and Fernando Romero as well as designers Ross Lovegrove and Michael Young to participate in creating these pairs, each requiring around a day to print on a sPro 60 selective laser sintering (SLS) machine made by 3D Systems.

All shown above, Flames by Zaha Hadid features pointy protrusions casting stellar silhouettes, UNX2 by Ben van Berkel looks almost like a hoof and Ilabo by Ross Lovegrove features open heals and toes. Below, the Young Shoe by Michael Young provides comfortable support on all sides, looking much more awkward, reportedly, than it actually feels when in use and Ammonite by Fernando Romero is abstractly patterned off of the spirals of sea creatures.

More on the process and materials from Dezeen: “The process starts with a container filled with powder, which is heated in places, as specified by a digital file. This fuses the material together layer by layer until the final form is built up. Once complete, the excess powder is broken away to reveal the design.Each pair was created using two different materials: the soles were printed in hard nylon, while the uppers were formed from thermoplastic polyurethane (TPU), which is softer and more flexible.”

To celebrate the 110th birthday of deceased British author George Orwell, famous for his dystopian visions of the future, Front404 roamed the streets of Utrecht adding colorful celebratory hats to all kinds of security and surveillance cameras.

Recent news about the National Security Agency has prompted a record-breaking uptick in sales of one of Orwell’s most famous works, Nineteen Eighty-Four (1984), in which state monitoring reached terrifyingly deep into the everyday lives of citizens.

From the activist artists behind the project: “By making these inconspicuous cameras that we ignore in our daily lives catch the eye again we also create awareness of how many cameras really watch us nowadays, and that the surveillance state described by Orwell is getting closer and closer to reality.”

CCTV has long been a subject for street artists, including the infamous Banksy, particularly in places with lax laws regarding the monitoring of public spaces … which makes sense, considering their works are not always legal, but often caught on tape.

New York has a long history of hidden and illicit venues – one that did not stop when prohibition was lifted. There is the innocuous pizza shop where dialing the right number in their phone booth lets you through a secret door into the pub. Or the various hole-in-the-wall places where you add your number to a wait list and hope for a call.

And then this, the now-defunct bar inside an abandoned water tower in Chelsea, requiring one to following a winding path up through a deserted building to find a surprise at the top.

Per the New York Times (images by Benjamin Norman), “The Night Heron was an invitation-only nightclub held illegally in a water tower atop a vacant building in Chelsea.” Guests had to make their way through a deserted building, then climb up a ladder to reach their destination.

All-nighters were common for this bustling little sweet spot, with last guests being let in as late as three in the morning. Live music reverberated within the wooden slats of the tightly-packed circular interior, with bottles of whisky reinforcing the retro (albeit a bit hipster) vibe of the whole affair. Alas, all good things must come to an end – particularly when they are a little less than legal in the first place.
