This is a pretty ingenious way to use unusable pieces of wood. Be it splits, or cracks, or just mishappen pieces that you can’t mill. Instead of burning them (which is what I would do), Italian designer Marco Stefanelli decided to fill the voids with resin that has LEDs encased in them. I gotta say, that’s nice. Especially the soft white color, instead of the cool-blue white of normal white LEDs.
I have a few pieces of wood that I was drying that cracked pretty bad. I think I’m going to try this on them.
