The printer’s proof of the Torchbearer GM screen came in the other day. Here are some pictures!
As you can see from the first picture (with a die balanced on top of the screen), this sucker is super heavy-duty. Also, note the numbers on the inside of the screen. You can use sticky flags or paper clips to keep track of turns. I recommend using flags of different colors to represent light sources. Place the flags on the turn the light will go out; when the turn flag reaches the light flag, the light goes out!
