Home automation / assistant devices are very much in right now, with companies like Google and Amazon battling it out to sell you small gadgets that guide you through your day and sell you stuff. It's like those cool sci-fi movies with 'smart' houses, but with extra spying on your shopping habits.
In any case, the Sufficiently Advanced YouTube channel has come up with a neat play on the idea, coming up with a system that responds to tunes from The Legend of Zelda: Ocarina of Time, played on an actual ocarina for good measure.
It's a fun, if not entirely useful, idea - check it out below.
Police services investigating house robberies should perhaps look for anyone skulking around with an ocarina.
With thanks to Joe Corbett for the heads up.
