The first Klein Bottles were made by Grandmaster Seifert Surface (Henry Segerman in RL) in 2005. He was the inventor of surface rezzers in SL, i think he is not active in SL actually, but his works are still the most innovative math examples inworld.

Seifert Surface has been to see my Klein bottle, and I have been to his on his old xyz sim. Zonja Capalini built a wireframe Klein Bottle on her Condensation Open Sim. I take it a bit further and provide a skin over the wireframe. I also make it a lot larger. I'm still working on animating the mobius ants. This Klein Bottle can be visited here:


Oroboros, anyone?

Breen Whitman

@Wizard Yes, thanks for the reminder re the Klein bottle at the Open Sim CondensationLand grid.

FYI for others:

ABout the bottle(and its single 2000 prim linkset):


available is full info and source scripts to build a bottle.

You're welcome.

Awesome work Wizard! Imagine if SL could generate and rez a mesh from a mathematically created struct.

And yay for mobygratis.com too!

Never ever enough Klein bottles! I miss Seifert Surface and Miki Gymnast's (hey Miki) and there spectacular work.

Seifert Surface (Henry Segerman in RL) is busy making 3d prints of his mathematical sculpture these days. You can see it - and buy it - here: http://www.shapeways.com/shops/henryseg
