Here's an idea for a contemporary loft or a small space. These bathroom dividers at the Brew House Hotel (in Kent, UK) offer privacy without blocking out the light. Using Smart Glass technology, the walls go from transparent to opaque with the flip of a switch.Smart Glass can be manufactured using a few different technologies, including liquid crystals and electrochromics. We found a good overview of the available technologies and how they work here. Companies that produce Smart Glass include LA-based SwitchLite, French company Saint-Gobain, and Minnesota-based Sage Electrochromics.
