Speaking of the MS Hololens: Is it still a thing and is there a community of 3rd-party developers around it? It showed a lot of promise when it was released.
They pivoted to military applications and I haven't seen much news about it. It looks like something out of the futuristic call of duty games. It looks super cool, but apparently soldiers didn't like it.
