that water system is sweet ass. this isn't quite as cool, but looks like something out of a sci-fi movie: maunsell sea forts
i don't know if anybody here has any idea what i'm talking about, maybe mamerro will know, but does anybody remember those plastic cards that had 2 or 3 images on one side with a whole bunch of little horizontal ridges, and depending on how you hold the card, you see a different image...it's not a hologram, but geeky like that. i've asked so many people and everybody remembers exaclty what they are, but nobody has any clue what they are called, or what the technique is called.
