       RE: https://oldbytes.space/@gloriouscow/116332911688709828this pointed out a weird issue with lightpens that I'd forgotten about:you can't point at black spots on the screen. Such a strange limitation. Imagine having to design a UI around not being able to have clickable black areas?

       @dysfun it sure is! but it's an inherent limitation of how the lightpen works: it's looking for light. black areas on a CRT do not emit light, so the lightpen can't see them

       @foone TFW adding dark mode is not just a question of recoloring.

       @foone Wow, I had no idea. Nothing that talked about light pens before mentioned that (not that I'd ever read much).

       @foone @dysfun I wonder if they'd work on an IPS display due to the backlight bleed
