DenysPetiukov very nice.
Seeing the laptop screen held open by a pen gave me an idea. To make everything still remain portable, someone could make a clear plastic case or back cover for the screen with a 3D printer or something. This way, you could use the laptop just like before without needing to hold the opaque cover open to let in light.
I also find an ambient-lit screen a novel solution to outdoor visibility. Instead of using excessive brightness and intense anti-glare coatings, the screen naturally is as bright as it needs to be. Rather than fighting against ambient light, the screen works with it.
