I have done quite a few searches for /hr/ Giger stuff. Sadly, it doesn't exist. It would take someone with Giger art books, a scanner, and some free time. That person doesn't exist, because a kindness like that is positively Christian, and Christians don't like Satanic biomechanical art. Therefor it does not exist. Just measly crap scans, 1024x768 at best, by Dutch drug addicts. Sad but true.
