Here's the guy who brought you the Atom Blaster. Yeah, I know that sucks, but in the design process he came up with some concepts and prototypes for stomp-mines.
His blog also gives you an insight into how they come up with some things, with sketches beyond both the gun and the mine. Those mine prototypes certainly give me grenade ideas.
