Very cool.
I’m also excited for the future of augmented reality. While the current attempts are interesting, I think it will be difficult for them to succeed with a dedicated design. Glasses are very fashion oriented. If someone can figure out how to get a display in a lens that works with any existing glass frame on the market they’d be onto something. No idea if that will ever be possible though, it may need something that attaches to the temples that extend to the ears.
