I don't think it's actually shipping, however the kickstarter project was funded.

The part you don't really see in the videos is the external transformer and wiring required.

I'd really like to see a great retrofit option for smart glass, but it's hard to build a product that has great light transmittance for retro applications. It's DC powered and has to be protected so it adds glare and reduces light transmittance giving a smeared appearance when it's used. That's why the current smart glass stuff is built in panels like they've shown at Cedia Expo, it keeps the PDLC in between the glass panels and provides a much better viewing window. It also helps hide the wires inside the window frame.
