Cinemas changing to 3D

There are no 3D cinemas near me and I'd really love to see a new release in 3D.
With more and more films showing as 3D presentations in certain cinemas, I wondered what it takes for a regular cinema to go 3D?
 
Im not sure but i think they have to put a special screen over the existing screen then get a new projector.
Im probably totally wrong though!
 
There are two main systems for modern 3D, one made by Dolby and one by Real-D, but essentially both require a digital projector, digital film server, and the appropriate 3D add-on. It costs about
 
The Real D system is rather clever, using one digital projector (with a circular polariser in front which switches for every other frame) running at a whopping 72 frames per second - required to stop you from noticing the switch in polarisation.

It has one major benefit over Dolby 3D (or Disney Digital 3D) in that you don't loose the effect by tilting your head.
