Glowing Big Boo
Big Boo chasing Mario in the night!
This is a combination of fluorescent epoxy resin as an inlay in an acrylic sheet, on top of an image in a wooden frame.
Notes
The image was taken from https://steamcommunity.com/sharedfiles/filedetails/?id=1915993656&searchtext=
You have to adjust the image (crop square) and print it in the fitting size. Depending on your printer, different scaling may be necessary.
To hold everything in place, I nailed a 6mm wood sheet to the back.
