Gruesome Halloween Party Food

Original image

You can make food to look like anything, including things no one would ever eat. All these suggestions come with recipes and instructions. Remember, for a scary Halloween party, presentation is everything.

To start off your party, offer your guests some White Chocolate Sugar Skulls. Kathy designed these for Dia de los Muertos, but they work pretty well for Halloween, too. More cute than disturbing, they set your guests up for worse things to come.

The Bloody Brain is an appropriately gruesome cocktail. The recipe, from Flickr user boomette, contains schnapps, grenadine, and Irish cream. The trick is in pouring the cream to keep it in a "brain" shape.

Don't these Eerie Eyeballs look delicious? They look amazingly like eyeballs, but the ingredients are marshmallow, gelatin, and cream cheese. Another recipe on the same page tells you how to make Awful Arachnidsfrom icing.

Awful Edible Fleshworms make a great entree. Under the Alienlarval appearance lies a delicious pork tenderloin wrapped in bacon!

What does a Kitty Litter Cakehave to do with Halloween? Hmm, we decorate with black cats at Halloween, and it looks pretty gross. But there is nothing in this recipe that's not edible. And of course it's served in a brand-new "pan". What you see is actually cookie crumbs and Tootsie Rolls. Kristian Hoffman has the recipe.

Barbara Jo and Barbara May love horror films and cakes, and have a website about each. Occasionally, they combine these hobbies to make masterpiece desserts, like this Killer Rats Cake, which comes with illustrated instructions. They also did a Zombie Cake and a Thorax Cake. See more cakes at Do It Myself, and horror movie reviews at They're Coming, Barbara!

The Bleeding Human Heartdessert looks like something that should be in an organ-donor cooler, but it's made of gelatin, with blood inside made of grenadine and corn syrup. The presentation is important; be sure to use a large butcher knife to slice the molded gelatin to achieve the proper flow of blood when serving. This recipe is part of a page with lots more ghoulish recipes.

If you serve any of these dishes, you may want to warn your guests about "surprising food" when you invite them. You don't want people to leave hungry and possibly sick!

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!
