Woodblock Art Answered
After seeing this https://www.instructables.com/id/Solid-Wood-Digital-Clock/, would it be possible to replicate this but light up just a solid image?
It would most likely require a CNC machine to pull off well, but if you took a piece 10cmx10cmx1cm of wood then milled out an image of something to 0.5m would it be possible to shine a LED through it to just bring up the outline while the rest of the wood is too dense/coated and you're just left with a image shining through wood.
I think you would be able to pull off some pretty cool artwork with it, but there's a few things that need to be considered; such a strength, the chance of it getting bumped is pretty low but with a thin diameter so the light can shine through it's probably quite fragile. Are there transparent fiberglass weaves/epoxy coatings that would add some strength while not ruining the effect? The other big thing I see is colors, would there be any limit factors with the different species of woods you can buy or is the main problem just getting a solid image lit up instead of just LED dots.
