Neil Thapen is a game developer who's been working this in-browser simulator (dubbed "Pink Trombone") since 2015. You, the user, are given fine control over every important part of the human vocal tract; in theory, you should be able to make all sorts of sounds. In practice, having such fine grain control is really, really hard to manage. The results are simultaneously impressive and hilarious.
by Edward de Bono. "There is a story of a man who painted half his car black and the other half white. He said he did this because he loved to hear the witnesses dogmatically contradict each other whenever he was involved in an accident. A wife tries on a new dress and loves it. Her husband who is with her dislikes it. She is looking at the colour and shape - he is looking at the price."
