For decades, lavish holiday window displays at department stores have been one of the first signs of the season. But have you ever wondered how the designers behind the windows create those enchanting arrangements? Here’s a behind-the-scenes look at everything that goes into making the holiday windows so magical at this time of year—from the best way to arrange lights to the pre-season all-nighters.

1. EVERY HOLIDAY WINDOW HAS A PURPOSE.

The holiday windows are supposed to make you feel something, says Jacques Rosas, New York-based artist, founder, and CEO of Jacques Rosas, which does holiday window installations in stores such as Godiva, Elizabeth Arden, and Bed, Bath & Beyond. Whenever Rosas is working on a window, he asks about the personality of the store, what they’re imagining, favorite decorations, traditions, and more—all starting with what they sell. “I try to pull settings that have nostalgia for them,” Rosas says. “I think the magical part is the nostalgia.” He loves the feel of an old-fashioned Christmas—last year, he decked out one store window with handmade stockings, old ornaments, and a real train.

2. YOU WON’T SEE MANY CHRISTMAS TREES IN THE STORE WINDOWS.

At least not any real Christmas trees, Rosas says. Usually, the windows are hot, dry places, so any live trees would dry out and die. They could also catch fire, so a lot of the newer buildings won’t use them even if they could create the right environmental conditions. “We tend to use a lot of fake stuff,” Rosas says.

3. YOU ALSO WON’T SEE ANY PRODUCTS.

While stores' windows throughout the year are supposed to sell products, this time of year is all about the entertainment, says David Spaeth, CEO of Spaeth Design, which does holiday windows for Lord & Taylor, Saks Fifth Avenue, Bloomingdale’s, Tiffany & Co. and Bergdorf Goodman. Sure, you may see a product or two in some of the windows (it’s not a hard-and-fast rule), but this is the time to seduce customers with gorgeous snowflakes or pretty (fake) trees instead of fantastic outfits.

4. BUT YOU WILL SEE LIGHTS.

Lights are what draws customers to the windows, and they can really make the displays pop. But you’d be surprised at how few lights will make a big splash, Rosas says. “There’s not a lot of lights—that’s a big mistake,” he says. "If you do too many, the reflection will play tricks on the viewer, and you won’t actually be able to see anything but lights.” Instead, he uses a few perfectly placed lights that bounce off each other. Rosas also tends to use plenty of wood composite, fiberglass, bark, paper, and plastic to create his scenes. But don't be surprised to spot other wacky items in holiday store windows, like Lite-Brite (yes, the retro toy), coffee stirrers, and even taxidermy. Anything goes when it comes to creating the perfect holiday window.

5. THEY PLAN AHEAD.

When the holidays start dying down, these designers are just getting started on the following year, says Michael Bednark, owner of Bednark Studio, a Brooklyn-based fabrication studio that is responsible for some of the Macy’s holiday windows throughout the country. Design talks start in January, and by March, the ideas are set. It takes two more months to figure out rendering, and the summer months are for fabrication (building the physical elements). Installation starts even before Halloween—by about mid-October, Bednark says.

6. THEY HAVE WORKING HABITS COMPARABLE TO VAMPIRES.

Ever wonder how holiday windows pop up like magic? That’s because the artists work through the night to put them up so that they’ll appear in the morning. Installation for the simpler windows usually takes six to eight hours, Rosas says. “We have to be like wizards,” he explains.

7. THE MORE INTENSIVE WINDOWS TAKE WEEKS TO INSTALL.

A regular window display is an overnight job, but the team working on the Macy’s windows pre-builds them inside the shop. There’s a fake window inside every single Macy’s store, filled with the entire holiday window display. “We pre-build inside the shop so we can make sure that everything fits,” Bednark says. The pre-build takes about four weeks. If it’s a go, it’s moved into the regular window, which takes three weeks.

8. TO MAKE IT LOOK PERFECT, THE ARTISTS TOUCH EVERY LIGHT.

The reason store windows look amazing while your holiday display looks just passable is because these designers really pay attention to the details. “When you decorate a tree, or you’re doing your lights and everything, the secret to really nice displays is to touch and adjust each branch, each light, and position everything as if everything was its own individual thing,” Rosas says. “That’s the secret to styling.”

9. WHEN THE SEASON IS OVER, THE DISPLAYS ARE USUALLY TOSSED.

Some stores will re-use the decorations in-house, but many will toss them because the décor is so unique. Basically, they don’t want to wear the same outfit two days in a row, Spaeth explains.

10. THE HOLIDAYS AREN’T THEIR ONLY BUSY SEASON.

We’re obsessed with holiday store windows, and they’re great for business. But these artists are busy year-round, Rosas says. In addition to doing store window displays for every season, they also decorate show rooms, do trade show displays, and even create sets for TV shows and product launches. In Rosas’ studio, they have two 7500-square-foot spaces, and they use these for creating fake store windows or for marketing experiences. For example, a yogurt company may hire Rosas to use that studio to build an entire yogurt set as a backdrop for a yogurt product launch. The yogurt company would then invite members of the media to the room, where they’d take pictures and do interviews. “We try to inspire people to write about [the company] there,” Rosas says.

11. IF YOU WANT TO REPLICATE THE LOOK, GET OUT YOUR CHECKBOOK.

To hire a professional display artist to do your holiday windows, expect to pay anywhere from $40,000 to $100,000 per window, depending on the number of details and amount of work it will take, Bednark says. In other words, making this kind of magic doesn't come cheap.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

Scientists Think They Know How Whales Got So Big
May 24, 2017

It can be difficult to understand how enormous the blue whale—the largest animal to ever exist—really is. The mammal can measure up to 105 feet long, have a tongue that can weigh as much as an elephant, and have a massive, golf cart–sized heart powering a 200-ton frame. But while the blue whale might currently be the Andre the Giant of the sea, it wasn’t always so imposing.

For the majority of the 30 million years that baleen whales (the blue whale is one) have occupied the Earth, the mammals usually topped off at roughly 30 feet in length. It wasn’t until about 3 million years ago that the clade of whales experienced an evolutionary growth spurt, tripling in size. And scientists haven’t had any concrete idea why, Wired reports.

A study published in the journal Proceedings of the Royal Society B might help change that. Researchers examined fossil records and studied phylogenetic models (evolutionary relationships) among baleen whales, and found some evidence that climate change may have been the catalyst for turning the large animals into behemoths.

As the ice ages wore on and oceans were receiving nutrient-rich runoff, the whales encountered an increasing number of krill—the small, shrimp-like creatures that provided a food source—resulting from upwelling waters. The more they ate, the more they grew, and their bodies adapted over time. Their mouths grew larger and their fat stores increased, helping them to fuel longer migrations to additional food-enriched areas. Today blue whales eat up to four tons of krill every day.

If climate change set the ancestors of the blue whale on the path to its enormous size today, the study invites the question of what it might do to them in the future. Changes in ocean currents or temperature could alter the amount of available nutrients to whales, cutting off their food supply. With demand for whale oil in the 1900s having already dented their numbers, scientists are hoping that further shifts in their oceanic ecosystem won’t relegate them to history.
