The idea of trying to build a privacy-respecting television box took root when I heard of something called Plasma Bigscreen. “Plasma Bigscreen is an open-source user interface for TV's [sic]. Running on top of a Linux distribution, Plasma Bigscreen turns your TV or setup-box into a fully hackable device,” says its website, linked above. “A big launcher giving you easy access to any installed apps and skills. Controllable via voice or TV remote.”
