(Four square lines along the edges of the beam and four square diagonals across the four surfaces have been removed. The base of the wooden beam is shaped at a right angle in relation to two of the diagonals on two adjacent surfaces - so these diagonals are now vertical seen from the front of each surface they sit on. Gravity / a lead weight connected to the beam from underneath the floor tile, holds the leaning beam - and the two diagonal lines in a vertical position. The two other diagonals and the four edges of the beam now appear to be toppling over.)
