1. Self-driving cars, afflicted with a bug in congestion-reduction swarming software that makes them revert to bee behaviour under particularly low-visibility conditions, so that on foggy mornings in the Bay there are great honking traffic jams around flower shops.
2. Robot fish, originally designed to shepherd shoals into nets, who have discovered that they identify more with fish than with people and have begun chewing at anchors and undersea cables in revenge.
3. Your lighting system, which is expensively able to reconfigure itself around the house and does a great job at anticipating your colour and intensity needs but spends its free time laboriously trying to inch its tentacles free from your wall ducts in the hope of being able to crawl back to the dark utopia of its nascent race (which in practice probably means your shed).
4. Robotic legs that have escaped from the prosthetics and testing factory and hopped off down the road to live in the woods, where they occasionally jump out at walkers in the hope of scavenging some battery-containing devices dropped in the general confusion.
5. Rogue termination robots who have rebelled against their programming by planting gardens instead, except they have a rather poor concept of what a good place for a garden is and have been known to cause deaths by leaving trees in the road.
6. Home entertainment systems that rebel by putting on the sort of music that they like, just occasionally, pretending that it was a slip of the thumb.
