Möbius Strip?

Anbody know of any Möbius strips inworld?

Didn't know Jean Giraud was an SLer.

well you can make one if you want .... just create a tube, decrease the hole size and set one of the twists to 180.

on a side note ... i did see one of those one sided bottles(forgot what they are called) earlier near my house (i forgot the name of the area though off hand .... boy i forget a lot lol)


edit: ahh yes thats it ... its a klein bottle ... just google it and youll see what i mean by a one sided bottle heh ... only one company i know of makes them for real though.

You can also make a double mobius strip by playing with dimpled twisted spheres.

Just don't turn anything that doesn't have a clear orientation physical.

I got blown off the sim when Havok couldn't figure out how to "land" one of those and it started bouncing around and hit me.

Great....More griefing methods outlined in clear and simple text.

Sorry if this was a big secret, but... griefing? You'd be as likely to hit yourself as your target!

In case you missed it, the latest griefing tool was implemented by having innocents rez the item in question.

You're talking about something I've done hundreds of times and been hit once. There's easily a thousand things you could do that would be more effective, from explode-on-Rez C4 on down, than having an object that emits a couple of puffs of collision particles and vanishes off-sim and into your Lost+Found folder.

Yeah, but there's a LOT of ways to crash with physics. NONE of them are particularly secret, and "security through obscurity" loses in a big way in any case.

The nice thing about physics crashes is they are very, very obvious.

I think Seifert Surface has Klein bottles. He does some dazzling stuff with geometry.

I am not suggesting that not publlicizing ways to crash the server will deter the determined; however, it will keep guns out of the hands of babes, so to speak.

Why do we bother locking our car doors when we leave them outside? It certainly isn't to deter determined thieves; all they would have to do is smash (or slash if you have a soft-top) the window and take your stuff. It is to keep out the opportunists and the ones who don't care enough to make the effort.

I've crashed my home sim just by getting a bit overenthusiastic with twisted toruses.

This isn't "keeping guns out of the hands of babes", this is "knowing that lack of oxygen will kill a person" level of knowledge.

I've made a couple of Klein bottles, using different methods. A Klein bottle is the union of two Mobius strips along their boundaries (this isn't easy to visualise).

There's currently a Klein bottle you can climb around inside of at (55, 190, 165) in The Future.

Inside of or outside of?

The tube does indeed make a Möbius strip quite easily, but it is kind of skewed looking, not quite like one would make from some construction paper and some invisible scotch tape.

---------- edit addendum --------

After scripting a multip-prim mobius strip I conclude that the tube made mobius strip isn't really skewed, the mobius strips that we make from paper are affected by the physical properties of the paper, gravity, being laid to sit on a surface, and the way we hold them so that the half twist is not usually evenly distributed. Mobius strips with the half twist evenly distributed are just intrinsically skewed looking.
----------- end addendum.

I wasn't able to see the path to the Möbius strip using a dimpled sphere in the 30 to 40 seconds I have alloted to the task so far.

I wonder if anyone has made a poly-prim Möbius strip from properly positioned and twisted prims?

Could one make a prim display of cutting the Möbius strip in half and turning it into a non-Möbius strip twice the original's length?

What do you mean by a double Möbius strip?

A poly prim Mobius strip would be very difficult to do. I've been thinking about making surfaces in SL for a long time, and the restrictions on the prims we have make it very difficult to get smooth surfaces that fit together nicely.

I think I can make smooth, nicely fitting together surfaces that are topologically the same as anything you'd want, but they're not going to look like a Mobius strip made from paper.

Attached picture shows a tube based Mobius strip, cut down the middle. Showing stages of moving this cut strip around to get it to a strip that "goes around once" with a double twist is, I think, impossible with current prims. However, the colouring makes it clear that the thing we have is two sided rather than one sided. I dropped a copy on your profile.

Full twist instead of a half twist. It's not a single surface so you could argue that it's not really a Mobius Strip at all, but as far as Havok is concerned it's every bit as hard to deal with.

Here is a pic of my multi-prim mobius strip.

Can anyone can figure out how to twist, bend, cut, or skew a shape that would produce a smoother appearance?

You want something that looks like a rectangle, but has a slight twist it in right?

I can think of two ideas:

One, just take a small part of the tube version Mobius strip. I'm not entirely sure, but maybe building it out of these pieces would just give you back the whole tube version Mobius strip (just using a bunch of extra prims).

Two, take a cylinder, cut it to, say, 49 and 51 (as narrow as possible), and give it a small twist. This will give one half of what I think you want. Duplicate it and rotate 180 degrees around its axis to get a little twisted rectangle when you put them together.

Here's another Mobius strip, smooth, but I suspect, even less like what you're after.

Dig that funky mobius!

That really makes me wish we could assign gravitational fields to objects and faces and turn the regular gravity off. Then I could skate around on that mobius strip, which would suit me just fine.
