Looking out the window of the designer's table room you see an apartment with a light turning on and off. Looks like dots and dashes. Or is is just a light turning on and off?

Begin with the big letters CONGRATULATIONS. T and S fall out. Now, Morse code: 1) On a ribbon (roller): --- = O 2) Mate signaling = U 3) Real signal (the only one, Indie) = I 4) What remains of the torn T (-): dash = Т 5) ASCII on a plane, 0x4f = О 6) Phone sound (need to turn camera towards it): beeping reads --. = G 7) Blinking light in the window: -.-. = С
Now removing the letters from the word CONGRAULATION (T and S already removed).
Getting the word NRALAN
Going back to the cypher table, setting up letters: in the original order, N and A - first, then second.
