no particular reference for this, just took some "slashes" and cut them
out of the walls with the expectation of using the inner wall in a
different color. designed, as much as I'd call it a design, for the Eva
stick, but this is mostly just me trying stuff at the moment

essentially, the whole inner wall and part of the outer wall gets cut
out of the piece, and a new inner wall piece (probably printed in a
different color, or with some design of its own) created that can be
seen through the outer wall's window
multiple window and inner options are possible, this is just the start
while I do other organization
