This has to be a win-win situation. Courtesy of The London Daily Photo Blog, an inventor called Demitrios Kargotis combined with the almighty power of the Royal college of art has come up with a machine that analyses your voice, and dispenses appropriate amounts of ice cream based on your mood.
Unhappy people get more ice cream, presumably (or rather, obviously) making them happier.
You could have seen this in action at the Icon Experiment. But since it’s now closed, you can’t. I don’t know about you, but that makes me think I’d be getting a huge scoop of ice cream right now.
