On the Subject of Hidden In Plain Sight
What are you, blind?
Why yes, yes I am.
See Appendix BLANK in Blind Alley for blank modules identification.
On the module are three numbers and a shape, but they are hidden to the naked eye. The only way to reveal them is by hovering over them, which will slowly make them visible.
Take the shape and median of the three numbers and find the corresponding cell in the grid below. Based on the position of this cell, place the other two numbers in the grid using the Numbers To Patterns section starting with the lowest then the highest. Hover over the status light when the last two digits of the bomb's timer is the number of white cells in the quadrant of the grid with the lowest number of black cells. Stop hovering over the status light in the same fashion and the module will be disarmed, but instead use the quadrant with the highest number of black squares.
