Microvision had some wearable laser displays which I tried out which I thought were really cool. Think they sold some wearables to Boeing for aeronautics engineers to be able to consult assembly documents while crawling inside wings, but not much came of it commercially. They eventually did some of the first laser based pico projectors.

Wonder how the present laser-rastering-your-eyeball displays compare to the latest micro oleds and whatnot.
