smart glass

[TP <to2000ny2000nospam@xxxxxxxxxxxxxxx>]

I would like to install a wall partition of smart glass. Has
anyone used smart-glass? The electrically charged glass that
changes from clear to opaque.   Some use a Liquid Crystal
Privacy film between two layers of glass. Anyone know if you
could purchase the film only? Or what the cost would be for a
piece approximately 5x5 foot in size?
