Green Tower Soundproof Glass Red Room Puzzle

The red house sits on the southern side of the Green Tower, just past the blue monitors on poles counting puzzle. Enter the red building and find the caged board covered in symbols on the wall. Press the two buttons in opposite corners of the room - this releases the gourd, but it also drops the soundproof glass into place, splitting the two players onto separate sides. A hidden button sits behind a wooden beam, on the left or right depending on the layout, and the player stuck on the symbol-board side can see it clearly; signal the partner across the glass to press it. That unlocks the caged symbol board and pops up a terminal on the opposite side showing the correct symbol order. Only one player sees the terminal and only the other can arrange the board, so use walkie-talkies to read the order out, or hold each piece up (E and Q on keyboard, LT/L2 and RT/R2 on controller) and let the terminal player nod yes or no. Once the board matches, press the button under the black screen; a correct match lifts the glass so you can grab the gourd.
