There's nothing we hate more on the face of the planet than cockroaches--the mere thought of them can send us into a skin-crawling fit. So we think that the geniuses at Bandai Japan who invented the "Hex Bug" should be shot or, better yet, ordered to serve a life sentence in a gigantic Roach Motel.
Just reading Technabob's description of the $16 bug-bots makes us twitch: "The Hex Bug series of miniature insect robots scurry along on six legs, just like real bugs," and will "change direction when you clap in their vicinity." Gross.
As far as we're concerned, we'd rather be attacked by RC tarantulas. At least we know it's possible to destroy those, unlike roaches, with a shotgun.
