I love spiders, not in a goth, doom & gloom way, but they're ace, fun to watch and aesthetically pleasing! The most bio-mechanical / tech, insect / creature there is! They catch flies, they build crazy webs across any gap, and they'll probably inherit the earth (together with rats and cockroaches). We've got one in our kitchen, with a big web across the window, if the web gets damged, it just repairs it, and waits for more food! Ace!
