There's 4DX screens as the Regal E-Walk on 42nd street in NYC and at the Regal Union Square. Regal is also building a new complex on Essex and Delancey and I suspect that will have 4DX as well. The Regal E-Walk charges $26.15 for 2D 4DX and $30.65 for 3D 4DX.

I think Disney uses a combination of scents that are "heavier than air" (hence they sink out of smell range quickly) or other moving air in the room to blow the scent away quickly after you get a whiff of it.

Probably their most famous use of it is in "Soarin'" where you get whiffs of pine trees, orange groves, diesel fumes (from helicopters) and etc. (They have since updated the Soarin' film so the scents are probably different from my memorized ones.)

I think that most of the molecules carrying smell will be heavier than air, which is mostly nitrogen (N2, ~80%) and oxygen (O2, ~20%). Still, without much air circulation, they usually will linger around for a while.

Now, it seems to be pretty simple to hide a previous odor by simply overpowering it with a new, stronger one (which is the primary trick used by most deodorants and room sprays).

Soarin' has some added advantages in delivering the smell. They're essentially constantly blowing air at you already, to create the sense of flying. They're blowing this air from behind the perforated aluminum screen. So, they can inject the smells right into this air stream and the same stream of air will also ensure quick dissipation.

Now, I wouldn't be so fond to blow all kinds of "smellified" air through a normal, perforated cinema screen. [Wink]

The new version is terrible in that respect. Unless you are sitting dead center, every straight line gets curved. The Eiffel Tower looks like it is made out of rubber!

I don't really understand why the digital version is actually worse at this. In a "pure optical" version, it's pretty hard to get it somewhat right, since all you can do is optical manipulation using lenses. In a digital world, you should be able to map the image in such a way that the perspective distortions are minimized, a rather simple distortion map in any high-end video editing solution could do the trick already and some advanced video-mapping systems can even do most of it on-the-fly in real time.
