The Art of Hay Sculpture

Montana Bale Trail

In the fall, a blogger's heart turns to thoughts of autumn decorations. Some folks go a little further than others in that department. Farmers and those with access to plenty of room and lots of hay have fun building large sculptures for the amusement of others. Here are just a few of those artful bales.

Snugburys Ice Cream

Every summer, Snugburys Ice Cream Farm in Hurleston, England, builds a giant hay sculpture and dedicates it to a different charity. In 2013, that sculpture was a Dalek from the Doctor Who series, to celebrate the show's 50th anniversary. It's 35 feet tall, and contains six tons of straw and five tons of steel. The sculpture ties in with the sale of the "Da-LICK" cone, with a percentage of sales going to Cancer Research UK.

Bauman Chiropractic Hay Bale Art Challenge

Bauman Chiropractic in Panama City, Florida, has a tradition of using hay bales in their fall decorations, which became more elaborate and fanciful over time. This tradition developed into a competition at the Bay County Fair called the Bauman Chiropractic Hay Bale Art Challenge. Charity groups are encouraged to enter a piece of art made of hay bales. All entering charities will receive $50, another $25 if they clean up after themselves, and more money if the public judges their artwork among the winners. The contest is this Saturday. The space travelers shown here are hay bales from 2011.

Killington Hay Festival

The annual Killington Hay Festival in Killington, Vermont, features giant hay sculptures, up to 30 feet tall! The festival runs from Labor Day to Columbus Day, in order to attract the many tourists who come to Vermont to see the fall colors.

What The Hay

The premier event of the Montana Bale Trail is the What The Hay contest. Serious farmers show off their hay and their imaginations in creating the clever hay sculptures, most using a pun involving hay. You can see those sculptures along the 22 mile route from Hobson to Utica to Windham in Montana. This year's First Place winner was "The Wizard of Straws" by Clint Carr

"Despicabale Me 2" by Judy Mikkelsen won Fourth Place and the online voting award.

Third Place went to "Hay-Bomina-Bale Snowman" by Nate Carr. See more of this year's entries and winners from previous years as well.

Artist Tom Otterness exhibited giant hay sculptures in 2009 near Mission San Juan, Texas. The entire work was titled "Makin' Hay," and featured several giant hay people making more hay bales.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

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!

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

To this:

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.
