Tech In Plain Sight: Incandescent Bulbs
(hackaday.com)
This is a most excellent place for technology news and articles.
The unrelated bit about touchscreens: i like the one in my notebook, combined with keyboard use.
Btw: illuminate a wall and you get that soft and dispersed light.
"Combined" is fine.
If you mean light dispersed from the wall, then yes. If you mean semitransparent something illuminated from the inside, hell no.
