perforated membrane

The top gradient image was used to make a pixelated image which in turn informed the cutting-pattern for the membrane patch. The size of the x-cuts  follow the darkness of the corresponding grid square on the pixelated image. The darkest areas have x-cuts which fill the whole grid square. The corners of the x-cut-flaps are pushed away from the membrane by a strut which increase in lenght as the cuts get bigger. Like in the previous model it is introduced an extra cut along the grid lines between two black grid-squares.
