Placing an 'active' Hex
Hexes can be placed at an angle (so two flat sections of the hex are touching the rock). If a downward force is created on the wire (or sling
depending on the hex) a rotating force will be created, camming the hex into the rock.
If the downward force (marked in purple) is created, a rotating force is created (due to the angle at which the wire leaves the hex). This rotating force attempts to turn the hex. The hex locks in place because the width of the hex (marked in yellow) is greater than the width of the rock (marked in green).
