Space Colony Island-4: Explore an 8 Kilometre-by-32 Kilometre O’Neill Cylinder in VRChat, with Curve Gravity!

The O’Neill cylinder (also called an O’Neill colony) is a space settlement concept proposed by American physicist Gerard K. O’Neill in his 1976 book The High Frontier: Human Colonies in Space… An O’Neill cylinder would consist of two counter-rotating cylinders. The cylinders would rotate in opposite directions in order to cancel out any gyroscopic effects that would otherwise make it difficult to keep them aimed toward the Sun. Each would be 5 miles (8.0 km) in diameter and 20 miles (32 km) long, connected at each end by a rod via a bearing system. Their rotation would provide artificial gravity.

“O’Neill cylinder”, Wikipedia article

There’s a new world in VRChat which is attracting a lot of attention! It’s straight out of a science fiction novel: an O’Neill cylinder that is 8 kilometres in diameter and 32 kilometres long, and it features curve gravity, where you can actually run around in a full circle to land up where you started!

(VRChat is not the first social VR platform to feature such a build; I have visited an similar O’Neill cylinder with curve gravity in NeosVR, writing about it here.)

Here’s the original announcement by its creator on Twitter, with the English translation below it, courtesy of the DeepL translator:

The world “Space Colony “Island-4” has been released! It is an enclosed space colony with a diameter of 8km x length of 32km. Please enjoy the huge scale of this cylindrical world!

Space Colony Island-4 is currently one of the most popular worlds in VRChat, so it’s on the VRChat home screen. Here’s a link to the webpage for the world (this page requires a VRChat account to sign in).

By the way, did you know that VRChat has just updated its Quick Menu user interface? Here’s a two-minute video with the highlights of the new design:


Thank you to Rainwolf for the heads-up!

UPDATED! Second Life Cyberpunk Urban Science Fiction Sim Hangars Liquides to Close

Wagner James Au, of the long-running SL blog New World Notes, reports that the Hangars Liquides sci-fi-themed sims in Second Life will likely be shutting down at the end of this month:

Hangars Liquides, a cyberpunk city created in Second Life by an elusive 3D artist known only to the SL community at large by her avatar name, “Djehan Kidd”, is among the virtual world’s greatest works — shadowy, moody, awesome.

Unveiled into the metaverse in June 2007, it has surely attracted hundreds of thousands if not millions of visits over its 12 year history. As its reputation spread through the virtual world, numerous cyberpunk roleplay groups flocked to it, adopted it as their oven, turning it into their staging ground for ongoing stories they created on the fly.

The blogpost includes an interview with the creator and an overview of the 12-year history of the project, so you might want to hop over to Wagner’s blog to read it in full.

I decided to transform into a cyborg and do a little exploring of Hangars Liquides before it goes away forever:

Vanity Fair is wearing:

  • Animated Headpiece: Queen Sarra headpiece by Shu Mesh
  • Cyborg Outfit with Skin Applier (Maitreya): Cyber Braver Lady by Bare Rose
  • Cyborg Arm, Cyborg Mask with Scrolling Japanese Characters, and Animated Upper Arm Attachment: Cyborg Geisha outfit (I picked all these up years ago in a different sci-fi themed sim hunt)
  • Cyber Prim Eye: by Omega Point (store no longer exists)
  • Animated Belt: VK Belt by Shu Mesh
  • Animation Override: Chubby Girl AO by [ImpEle] (free from the SL Marketplace). This is a nice, simple, calm, free AO with no crazy movements.

Vanity is also wearing:

UPDATE July 18th: Djehan Kidd has launched a crowdfunding initiative to save Hangars Liquides using Indiegogo. She has fifteen days to raise 6,000 euros (CDN$8,798) to keep the sims running for another year, and she is giving donors who give CDN$147 or more their own apartments in Hangars Liquides. So, if you’re interested, feel free to show your support.
