The building I work in has rolled out a new "destination dispatch" elevator system using Schindler's PORT technology. Not all that notable in and of itself, but the screens seem to me like they would make a fantastic HA control. They are incredibly solid and nice to the touch, come in a pedestal configuration as well as wall mount, and in a variety of colors. The accessibility button at the top is optional (although I'm very glad that our building opted for them). There is also a proximity card sensor underneath--that could double as a night light....
Alas, I don't think that they're available to the public.
