Semenov Dahir Kurmanbievich, the mad-scientist engineer whose work we've been looking at lately, is capable of some seriously outside-of-the-box thinking. His wild design concepts, all of which combine the fantastically improbable with just enough of the hey-that-might-work factor to keep them appealing, run the gamut from the primarily peaceful domestic concepts we've seen so far—folding houses, drive-in supermarkets, dental in-mouth CNC machines—to some terrifying killing machines.
