When someone says they're playing a sad tune for you on the world's smallest violin, you usually have to take their word for it. Now the creative minds at Design I/O have found a way for actual music to accompany the sarcastic hand gesture.
In the video above (spotted by Gizmodo), you can see and hear someone producing a melancholy violin melody by rubbing together their fingers over a small device. The gadget uses a radar-based chip from Google's Project Soli that senses minute hand movements. When the player speeds up his or her fingers, the music becomes faster in response.
Soli was originally created to control devices like smart watches with subtle gestures instead of typing awkwardly on a keypad. Using it to make your lack of sympathy for someone even more apparent may not have been the intention, but it does look like a lot of fun.
