Incredible cool!!!!!!

Laukosarg Svarog

Seifert recently gave me a tour of the house, really very cool !!
It's really funny when you take a wrong turn and end up in an upsidedown room. Masterful coding :)

Robbie D

I just had one of those, 'oh I get it', it's like, errr... 'oh no I don't' - moments, I guess I need to go vist asap, but the concept sounds truely amazing to me.

Elle Pollack

The embedded video doesn't seem to be working (least not for me), direct linkage to the video pages are http://www.youtube.com/watch?v=ubk4Mq8d5Rk&search=seifert and http://www.youtube.com/watch?v=OEUDoQCECgA&search=seifert

Chalk another one up for Sei! It's much cooler than *my* home in The Future (I'm a deadbeat living in a big culvert pipe with a solar pannel and cantenna powering my computer)

Luciftias Neurocam

Nicely done, Seifert.

Joe Rybicki

Here from Boingboing, great story.

Just a point of clarification, though: In the short story, the architect builds the house as a -disassembled- hypercube, so eight cubes arranged very similarly to the outside view of this house. The earthquake causes the house to collapse into itself and turn into a true hypercube. No extra dimensions are necessary.

Sorry, Heinlein geek over here.

Vlad Bjornson

Great job Seifert - that is truly some 2nd Life architecture! Now we need an article on that animated, 3d projection of the Hypercube that you showed me a while back. I have tried to explain it to several friends, but I can't wrap my brain around it far enough to make any sense. :D

Relee Baysklef

Now that was great. XD

I had a suspicion that he was moving the rooms; either that or moving the avatars.

Hamlet Au

Thanks for the headzup, Elle, I just added direct links to the YouTube vids in the story.

Gwyneth Llewelyn

I'm confused :) This seems to much magic to my poor head, I would *never* find out what was going on without the movie from "far back".

Cool? No. This is mind-boggling!

*blows up her prim-tortured brain*

You're a math wizard, Seifert :)


very, very nice. congrats, amigo.


Ordinal Malaprop

This is quite a superb creation, and something which reminds me why I ever started studying pure maths in the first place. In my relatively advanced years I appreciate being taken back to my old level of wonder.

Gwyneth Llewelyn

Ok. Let me rephrase all that. I've just went through the weirdest experience in SL, after testing this out "in the flesh", so to speak. I was quite sure I understood what was going on, but the illusion is *perfect*.

My poor brain is simply not wired to understand how this works. I'm bedazzled and beffudled. Ack. I need a shrink to put my mind in order again. I truly hope that this doesn't become a trend; SL is getting more and more fascinatingly confusing these days; or is it confusingly fascinating? :)


Brilliant. Gives me the same other worldly feel I had as a kid reading Edwin A. Abbott's Flat Land

It would make a really good brain teasing puzzle game.

Elle Pollack

The owner of The Future recently installed a telehub in the sim, so everyone who's clicking the slurl link to get through are landing in our Grand Central Station. Just follow the signs on the ground and the transport tubes from the telehub to get to the "workshop platform" where you'll be pointed to a teleporter that will put you inside the house proper.

Elle Pollack

Almost forgot to add: this story made the Digg frontpage (over 480 diggs so far)!

John Cartan

Nice! For more information about higher dimensional hijinx, including a floorplan of Heinlein's 4-cube, a 5-cube, and even a visit to a 9-cube hotel, see the URL above.

John Cartan

Oops! I meant to say: see THIS URL:

Cartan's Triangle

Jeska "Linden"

Great find, Seifert gave me the tour last night and I have to admit I was quite disoriented!

Nicholas Lawson

You know that description of the rooms folding around each other, that could very easily be a plausible reality that surrounds us right now. We would never know if we were really on a morphing spaceship that was floating in space, if it was always set up like that for everyone ...


I have to say that the Crooked House kind of creeped me out. I couldn't escape! I yelped when I ran into another resident wandering around.

Reminded me too much of "the Cube."

Hamlet Au

Actually, there's a rumor that some other Residents have built a working cube inspired by, well, *The Cube*.


yeah, i've seen the build inspired by *the Cube* - a giant array of rooms where sometimes the cubes move about.

i believe the coding was done by a guy named Seifert Surface. you might ask him for a demo.


Hamlet Au


Senor Surface did not inform me of such!


I've been trying to find this place and I can't seem to get to it. The slurl doesn't work for me.

Dyne Talamasca

I built a disassembled and collapsed rough model of the house exterior, inspired by just that story, back around October/November, but I wasn't crazy enough (or familiar enough with SL at the time) to try to figure out how to make it functional. :)

Nebula Gray

The structure's cool, but I would imagine being on the surface of a "real" hypercube would be one of the following: if you're on the top or bottom of it, you would be floating; if you were on the sides, you'd "fall" to the bottom due to gravity. Except you wouldn't have to worry about hitting the floor--you'd just float once you got to the bottom. Then again, since we're talking about a 90 degree angle in 4-D space, you'd probably just be able to stand hovering above the door to the bottom room.

Primitive Hax

How would time pass inside a 4D hypercube?
I'm probably confused, but doesn't "time" in Einstein's 4D spacetime happen all at once?
Does this mean that if I lived in a hypercube with a (hypothetical) wife, and she asked me to clean the living room... Without lifting a finger I could nonchalantly reply "I already have or haven't dear"?

Dammit, I'm sick of being an ignorant 2D bug, doomed to blindly wander around a stretchy rubber 3D topology :(

This guy's a genius, but I hate him so.

Farnham Farrjones

Could you build "Rufo's Fold Box", from The Glory Road with this tesseract scenario? As I recall, it was a smaller, portable version of tesserocity, in which Our Hero could ask Rufo, his retainer, to extract everything from a howitzer to a banquet table, depending on the mood of the evening. To steal another quote, "Brain hurts, rest now".
Analog Guy, Farnham Farrjones

Lionel Oliva

Awesome article, clever concept! I hope to find something on Escher sometime soon.

Seifert Surface

The Crooked House has moved, it can now be found at: http://slurl.com/secondlife/xyz/126/57/501/


What is this? I just saw a crooked house and clicked on the link in google. What is this?


2022! :)

Wagner James Au

Thanks for going deep into the deep links! :)
