I wasn't aware of these glasses, pretty cool. Not sure I'm ready to drop that much money on a pair with prescription lenses though.

Would be useful to have my multimeter display in my field of view when heads down debugging a circuit. There are a few bluetooth meters on the market, so I think this is doable?

Looking at the SDK, the fixed LVGL font is a bummer. Ideally I'd like to have a raw framebuffer to control, though I imagine this is difficult to do over bluetooth without blowing your power budget. Maybe you could have a custom indexed tilemap and push sprites around?
