So this never materialised as a flash animation, although I did storyboards for it. I never wrote a song about it, but I wrote a text and a legend behind it where the pipes are actually tiny veins in the eyes of the enemies of some really forgotten king. The enemies walk forever in the maze of veins, but one day the incantation might be broken and these monsters would be set loose on the touristic city (I imagine a version of venice) where the hall of eyes exhibit was housed. One day a monster would find himself in this strange place with a guestbook on a plaque and tourists walking around with cameras and children. And maybe would berserk or would fade into a dream again.
And I tried to do it as a dhtml nightmare back in the nineties.
But Half life 2 is the best outlet for it. Again a distorted deathmatch map: the only weapon you're given is the crowbar, you seldom meet other wanderers, the tubes are randomly generated, go on far too long and small bugs run around giving 1 health each time. The tubes are also a boy's height. So you have to crawl at all times. And then there's random teleporting going on. One random teleport that happens rarely will take you to a museum, where a hall of eyes lines the side, where you can go on a rampage and kill tourists, but with some physical constraint to make it harder (like guards with actual guns). I think the experience of someone using it would have to usually be just the cramped sensation of wandering around in the dark in a tube, which sometimes goes underwater and where you sometimes find bugs, and it's never the same and then you get bored and leave. But if you stay in it for a really long time, you might find another wanderer (and both die from the ensuing crowbar fight) or you could get teleported to another part of the tubes or if really really lucky to the outside tourist world. But most people would just get bored and leave. And a few people would hopefully get claustrophobic and related emotions to do with confinement and dark tunnels up ahead.
