A Disturbing Little Tour Of Rogue Taxidermy

Rogue Taxidermy is a folk-art form where you use dead animal parts to create some new, unique creature that never could have existed... but should have! So appropriate for Halloween.

The folk art form of rogue taxidermy seems to be rooted in the midwestern United States, and can be considered a hallmark of Midwest Gothic. The most famous group is the Minnesota Association of Rogue Taxidermists. One typical truckstop chimera is the jackalope:
Rogue taxidermists got so carried away with the jackalope thing that they managed to infuse the critter into the North American culture at large, and now no roadside truckstop is complete without a mounted jackalope head on the wall. There's jackalope tattoos and faux nature documentaries and hundreds of photo manipulations. Jackalopes are world famous, a triumph of rogue taxidermy! Future popularity to a similar degree may be won for the hodag:
Or the fur-bearing trout:
As you can imagine, there's a huge crossover between the rogue taxidermy and cryptozoology worlds. Whether through intentional attempts to hoax the public, or tongue-in-cheek attempts to hoax the hoaxers by going "Look, I found one!"

Perpetual motion museum - bent your mind watching people try to bend the laws of physics

"Hey, guys! I've invented a design for a 125% efficiency motor, and if you all fund my Kickstarter in return for a share of the profits in my new motor company, I can eventually build 500 of these things on a 3-ton scale and produce the world's first kinetic power generator! Who's in?"

"Hello? Anybody?"



Welcome to the world of The Museum of Unworkable Devices, a huge, engaging site documenting one of the most futile fields of study in engineering, the history-long quest for perpetual motion. Within, Donald E. Simanek serves as a James Randi of the engineering world, showing us endless attempts at overbalanced wheels, spinning magnets, wild stunts with hydraulic pressure, and machines which baffle the limits of the imagination as surely as they thumb their nose at Newton, Archimedes, and Einstein.



The site also works as an education in physics principles. For instance, did you know that the ball along the bottom ramp of this device reaches the goal first?



Be sure not to miss the FAQ, "Why won't my perpetual motion machine work?", where Simanek explains it all like you're 5. Ought to be required reading in high school science at least.



Perpetual motion ties into a related fallacy emerging in computing.

I've recently investigated thoroughly the latest cult, sure to usurp Scientology as the most tenacious, known to some of you already as the "Singularity". The "Singularity" is the point at which computers are supposed to surpass human brains in intellect, at which point they will continue on their own to build even smarter computers, and so on ad infinitum until we're all living in the Matrix.

I'll stop for a paragraph so you can fight the urge to puke. Deep breathing helps.

The idea of  the Singularity (which has been "just a few years from now" since about the 1700s) and the bogus search for a perpetual motion machine is evident when you consider that computers do nothing until a human writes a program for them. And it's quite daunting for a human to write a program that causes a computer to be smarter than a human, since by definition the human is not smart enough to write it. And computers really are not smarter than humans at anything, they just appear to be in certain fields by virtue of brute force and speed - for instance, they beat you at chess by calculating six moves ahead from every possible move, including the ones we would eliminate through common sense. Like the would-be perpetual motion inventors, Singularitarians seek to boost the IQ of machines by making them smarter than they are so they can write themselves, just like overbalanced wheels seek to gain infinite momentum by making objects be heavier than they are so they can push themselves.

Every time, I pin down some Singularity zealot and ask them "How could you write a computer program that was smarter than yourself?" The answer is always "We'll have a computer program write the program!" I bounce back "OK, how do you write THAT program?" "We have the computer write that program, too!" Oh, I see. We'll write a program to write a program to write a program to overwhelm common sense, just like we'll trick those nasty old laws of physics by spinning a wheel inside a wheel inside a wheel...

How English sounds when you don't speak English

These two actors do an excellent job of having a conversation in pseudo-English, just to show how it sounds to a foreign ear. Bizarrely, you keep thinking that you could make sense of what they're saying if only you listened one more time...

Fire rainbows in the sky

The concept is called a "circumhorizontal arc". It's an atmospheric phenomenon in which sunlight strikes airborne ice crystals to produce a rainbow effect. Four things have to happen for this to be seen:

  1. The sun has to be higher than 58 degrees above the horizon.
  2. There has to be a mild haze, such as cirrus clouds, slightly overcast, a marine layer, etc.
  3. The clouds must contain flat, hexagonal ice crystals.
  4. You have to be standing farther than 55 degrees latitude away from either pole.
For these reasons, the rarity of the event causes it to only be visible from certain parts of the world at certain times of the year. In North America, it's most commonly observed inland and to the north during the colder months, although as long as there's ice in the clouds and you're standing in the right spot, it could happen anywhere.

Because of the rarity of the event and the strange cloud formations that sometimes occur in conjunction with it, the phenomenon could be mistaken for things like UFOs and other conspiracy-laden legends.

The Hebrew psychologist who thinks Moses was stoned out of his melon

Hallucinogenic drugs have often been supposed to be responsible for many fantastic accounts of miracles and general religious phenomenon, from the Salem witch trials and panic to various sightings of the Virgin Mary. However, not many dare to apply such a theory to one of the head honchos of half the religions in the world, indeed, the man who could be said to be the basis for all modern law.

But Professor Shanon has had enough of this reverence for miracles. In his paper Biblical Entheogens: a Speculative Hypothesis, he details numerous parallels between visions and experiences of Moses and hallucinations experienced under various psychedelics.

Pause and consider that this is not at all a far-fetched theory. Early humans had no concept of mind-altering substances beyond alcohol - to them, if you ate something, it either killed you or it didn't. When some attachment between altered states of consciousness and a previously consumed food did eventually dawn on people, they immediately took it for a connection to spiritualism. Marijuana, ayahuasca, peyote, and the famed "magic mushrooms" have all been connected to spirituality in beliefs such as Shamanism and Rastafari.

In the event depicted as the "theophany", Moses' experience includes thunder and lightning, a pillar of fire, trumpet calls when no instruments are present, the whole mountain smoking and quaking, and a voice booming out of the sky. Anybody who's experimented with doses of LSD or other psychedelics can relate. Note that it's not merely a matter of seeing and hearing hallucinations; one's thoughts and emotions become very confused during such experiences and one's own ideas may become the strangest experiences of all. Feelings of religious awe and emotional epiphanies are frequent and common in the psychedelic experience, even in doses not sufficient to trigger visual and aural hallucinations.

The problem is that the exact drug available in the Jerusalem area at the time that could have caused such an experience is not known. However, even plain old rye bread can become infected with the fungus known as ergot, and there is evidence of cases of ergot poisoning present in nearby Europe. Shanon's theory merely points out similarities between Moses' reports of miracles and the effects of drinking Ayahuasca, and leaves it at that. This drink is prepared from plants of the psychotria genus, which only grow in tropical regions.

This is not to say that such a drug would have to have been imported. There may have been species of another plant with psychedelic effects growing in the Mediterranean region around the 1500s B.C., and simply become extinct by now. One such example that we know of was silphium, a plant used to produce a drug widely thought to have been used for birth control - among many other uses.

Becoming a real life oil painting


Yes, that's a model captured by artist Alexa Meade within a 3D oil painting simulation. Border between art and life blurs further. More here.

The Visual Puzzle in Hans Holbein the Younger's "The Ambassadors"


You've probably seen this painting making the rounds on optical illusion websites:


It's become popular lately thanks to Google Art Project, the first attempt at putting high quality scans of paintings online for access. The curiosity value, of course, comes from the distorted view of the object in the extreme lower foreground, which resolves to a skull when viewed at the right angle:


In itself, the anamorphic perspective of the familiar momento mori technique is a splashy, attention-calling element. But why spoil an otherwise excellent Renaissance work, filled with masterful technique, with such a tacky carnival trick? Art scholars argue this motivation even today.

The rest of the painting is a double portrait, showing a kind of duality between the church and science. There is a cleric to the right and a merchant to the left. The objects scattered about the table between them continues this theme. In fact, like a David Lynch movie, the painting has various symbolic elements which are open to conflicting interpretations. But of course, like a car honking its horn, that stretched-out skull keeps distracting us.

Could it be that he was thumbing his nose at whomever commissioned the work? Was he adding the skull as a way of saying "this whole painting is a joke; don't take it seriously!" Was it to impress a certain person? Did he add this to cover up some mistake in the background? Is it perhaps a pointer to other thematic clues elsewhere in the painting? Is there some significance to where the painting would have originally have been hung - such as on the right-hand wall of a staircase near the bottom?

History may never know the motives of 16th-century Northern Renaissance painter Holbein.
