Crushed between two portals, feelin' like a fool
Using' both of you is breakin' gravity's rule.

Kinda gives me a 2001-2010 feel. All these portals are yours except attempt no portals here.

Also Sprach Zarathustra plays.

A shot of the moon in space.

The camera pans down to the planet Earth, then pans left to reveal a GLaDOS Personality Core as the music hits the crescendo.

If they didn't intend the Source Engine to do that, how'd it know to play that music then, huh?

I think I sort of get what's causing this. It's video feedback rendered in a digital environment. It's what happens when a video camera looks at a display of itself. Which is what happens between the portals.

The machine brought the two portals together very quickly, but not instantaneously. Which means that Chell probably would not find herself in some weird non-space. Her foot would have crushed her head in the very brief moment between when the portals were too close to each other before they were completely adjacent.

Two hours of analog video feedback with chiptune accompaniment.

That's something that confuses me, though. In the developer commentary tracks for Portals, there's a brief digression about how they had to limit portal loop depth to prevent users from slowing down or crashing the renderer when portals fed back on themselves. So I wonder how the video got its infinite feedback.

Maybe there's a terminal command for adjusting that limit.

Well, yes and no. From the notes about the video: For the record: Portals can move. In Chapter 5 (The Escape) at the thirty-third level of the game, you have to place portals onto moving panels to cut neurotoxin generator tubes by using a laser - https://youtu.be/B2gBNwT6aqU?t=2m11s - This gameplay mechanism is not activated by default, so a special command was used to achieve the experiment. I created that simple test chamber by myself in Portal 2 SDK.

And here we see the fractal nature of player choice represented in the very game mechanics itself, with each action branching into infinite future actions. Will Chell, controlled by the player, dive into the portal to the left or the right? Both choices lead to the same outcome, another choice, but by a different path.

I'm more impressed that the thing didn't just seg out. Good on the Valve dev team.

This is a really, really excellent stand alone mod with a good story. It's also difficult. Right from the beginning, you are spending a pretty long time on each puzzle, just trying to suss out the possibilities. However, it's worth doing, especially if you wish Portal at times had harder puzzles.

There was a trope in new wave SF stories of hyperspace navigation done through some form of direct experience and psychic manipulation of the superluminal universe. The navigators tended to either go mad, or be mad in the first place - it was all heavily informed by LSD, although I was largely innocent of the existence of same at the time I was first inhaling the local library's SF section.

This is pretty much how I (or the 11 year old me) imagined such navigation. It's also how the 50 year old me imagines navigating through things like a wideband representation of the radio environment, or elements of quantum or cosmological-scale reality...

I gave it a try, but it didn't seem quite the same, which left me a little disappointed. I'll give it another go, though, if you guys say it's worth it.

Meh. It's a nice piece of machinima, not an exploration of the limits of the Source engine. Graphic recursion, third-person camera, and video feedback are hardly new frontiers; anyone who's spent enough time in spectate mode in the various multiplayer games using the engine will be familiar with them.

That's probably a sufficiently small percentage of humanity to justify saying "Hey, seen this?", though. (I've been playing with video feedback since forever, which I still think itrippy and cool and weird. This is quite the upgrade.)

I don't play videogames, no matter how massively multiplayer, so I don't have anything with a GPU in it. For access to a creative, malleable, hackable space like this, though, where others of similar bent hung out, I'd pony up whatever it takes. I'd want ways to import data and plumb it in, and tools that compensated for me having ideas above my coding/graphic design skill set. Sorta combination 60s new-wave SF reality reconstruction meets Minecraft.

thatwhichfalls - ahahahaha... I don't remember the story, but the precis you link to makes me think this was one of those that completely crystallised some of my SF tendencies. (And, of course, the outsider/pathfinder/evolved character in Delany;s work carries other significances the 11 year old me was also unaware of...)

Time for a refresher course. And the 'how would this work in a digital reality-morph environment' supplementary.)

I'd like to see this again with Atlas or P-body as the player model, because, despite the opportunity for pun, above, the top half of Chell's head and face floating in a surreal void is a little spooky.

The machine brought the two portals together very quickly, but not instantaneously.

I forgot that in the Portal Universe that exists when you play the game, the quantum granularity of time is much coarser. That is to say, the Source Engine's equivalent to the Planck Time is enormous. I mean, time in the computer progresses in discrete steps that are much longer than the ones in the real world.

Which means that it's entirely possible the portals are brought together instantaneously: one computer "moment" they're far enough apart for Chell to not smash into herself, the next computer "moment" they're adjacent and she's stranded in the "somewhere else" seen in the video. I don't know how the Source Engine works, but it's possible those moments are shorter (maybe tied to how high your frame rate is) on more powerful computers. Which would mean Chell's chance of surviving increases the older your computer is.
