This is a totally bizarre video.
The project is called "Dynamic Terrain," by janisland, and it certainly took a lot of work, but the movement of this thing grosses me out a little. It reminds me of the bog of eternal stench from Labyrinth.
The concept of a plane (wall, floor, ceiling?) being able to adjust to suit different functions is a perfectly acceptable one. I would definitely like to play around on this, if nothing else, and I guess the speed of the undulations (plus the weirdo music) is just to exaggerate the concept. It's still like something from an alien movie, though.
