claudia's Journal: Self-Healing Minefields

"Utilizing commercial off-the-shelf computer chips and "healing" software, the networked minefield detects rude attempts to clear it, deduces which parts of itself have been removed, and signals its remaining munitions to close the hole using best-fit mathematics. The mines, which can hop, then redistribute themselves, frustrating the enemy and quite probably terrifying him in the process."

Frustrating the enemy? How delightful to hear they won't kill the enemy.
