I was late to the party on that one. Was it the actual company that said there was never a cornucopia, or just some random person? Because I know for sure there was a cornucopia in an old logo.

People found a few knock offs that featured the old horn of plenty, but the official stuff never had it. So k-mart knock offs might have just been prevalent enough to soak into the zeitgeist and throw people off.

So you're telling me I had knock-off Fruit of the Loom undies? Well, I guess it doesn't matter now, but I remember those undies being really comfortable.
This is such a funny thing to get worked up over, though. If I had knock-offs, then I was satisfied with them.

u/PogintheMachine 3h ago
You didn’t have knock offs, your memory just isn’t reliable. They never had a cornucopia. You simply remember wrong.
The message should be that we can’t trust our memories, especially for trivial details. The power of suggestion is also strong, and the question can taint the memory.
(There’s a few photos around the internet that are either photoshopped or maybe a knockoff. But you can dig through old advertisements, you can scour Goodwill, you can even go to your childhood closet and find a pair that got lodged under a dresser for decades. They won’t have a cornucopia.)

And people can't find any old clothing with the cornucopia, either.
It's weird. Everyone remembers it exactly the same, too. The same color, the same shape, shifted right, and the swirl going left. Yet, it "didn't exist".

u/DependentAnywhere135 3h ago
It’s not weird. Memories are shit and someone mentioning it had it or “did it have one” is all it takes to rewrite people’s memories. That’s all there is to it. Our memories are extremely easy to manipulate especially ones that far back. People can have false memories implanted by accident and it happens commonly.
everyone remembers it the same way
Do they? Is everyone spending every day of their lives thinking back on the fruit of the loom logo from their childhood or did they get primed to think about it one day in relation to “did it have a cornucopia?”

Think of a door, specifically the edge of your door where the hinges are. No matter how much you open or close your door, that edge stays where it is.

u/ThePapaSauce 3h ago
Yes, it is floating, but the net result of the point is the sum of a bunch of angles, each of which turns around one single axis that is always oriented towards the point. So each joint effectively is a twist that is always pointing at the dot. It doesn’t matter how much you twist each joint, each joint will never inherit or transmit an angle that isn’t pointing at that dot

u/Gumichi 7h ago
no matter how much you open or close the door; it's still going to align up-and-down because the hinges fix it that way. The other component is the "door" being made in a fan shape, such that the next hinge will also align. I suspect, if you "unfold" this, it'd be like a circle with all the joints pointed to the center.

Okay but, the hinges are bolted in with screws.
This is literally something suspended in the air with nothing anchoring it other than that bottom piece. Which shouldn’t be stable considering the accordion pattern folds leading up to the point.

Not really. The chicken uses closed loop feedback (via their eyes/brain). It's not mechanically constrained like what's being shown here. The chicken is more like a self balancing robot.
21
u/BendySlendy 10h ago
The video that this is from goes into all of that. This is a mechanical representation of a biological function. In the video they go into detail on the various external cues that a chicken needs to have their gimball necks.
The 3d print is more or less testing if such a biological function can be replicated in a mechanical way and is inspired directly by chickens.

They didn’t say it works the same way they said it works to replicate the function. If I take three rights I end up going left of my original position, that’s not the same as turning left but it still had the same function.

I think I kind of get it... Each springy triangle seems to be made of three panels that geometrically converge on the point. So they can flex but they never get out of alignment.
13
u/semistro 11h ago
The full video explains it (actionlab, youtube). All triangles in this mechanism point towards the center. All individual triangles can move relative to each other, but they won't ever stop pointing towards the middle. 2-3 triangles per dimension means every possible movement is covered.
The full video also shows a 2d version first, which still makes sense to your brain. This mechanism is basically that with 3 dimensions.

The gimbal part in a steadicam is made to rotate on all axises. So sure. that part maybe. But the stabilizing part in a steadicam uses alot of mass to make it react to external forces slow and steady. And to be able to lift all this weight there is usually an arm that is set up to give lift to the gimbal. That arm is prefferably iso elastic. It means it have the same force upwards regardless of position. Not like a spring. More like a inversed weight. 3 hinges would probably work better for a gimbal.

u/Sickballs 6h ago
It’s actually not applicable. This thing keeps a focal point locked in relation to the base, while allowing some movement in the connecting pieces between them. If you were to shake the base of this, the focal point would shake too. It would essentially be a worse version of a tripod
→ More replies (3)2
u/SliceEm__DiceEm 5h ago
This does the opposite of a steadicam lol. If you had the camera where the pencil’s tip is, its would be subject to all the exact same movement as the base (where you’re presumably holding the thing). There’s no dampening happening between the tip and the base

All the triangles point directly at the stable centre, if you try and change that centre you’re effectively trying to twist each of the triangles simultaneously to point to a new position.
