The Boundary
Captions available
The idea
Every weighted-sum-with-threshold divides the space of possible cases into two sides, separated by a straight boundary where the score is exactly zero.
In practice
Melons as dots on graph paper: change a weight and the line tilts; change the balance and it slides.
Where people slip
One straight cut is the whole geometry — what a single cut cannot capture becomes this unit's cliffhanger.
