Hi! I've been watching this amazing show, and lurking some captions of certain device in a scene, I noticed that, although is this future world, V-slot rails are top notch technology. (Be warned, Spoiler ahead) http://i.imgur.com/Ejb1A1k.png http://i.imgur.com/BWYtkwe.png It seem V-s has a bright future on some areas of IA. Props to the makers of HBO's staff.
Hate to burst your bubble but that's not V-slot. Zoom in closely on the left side of the first photo and you'll see ridges along the rail. 80/20 has a pattern like that and others may too, but Openbuilds doesn't.
