Thank you Raphaël Pluvinage

This is a pretty amazing use of the Arduino card. You can read more about it here.With a little agar, salt and color and a game board made of capacitive sensors you too can have hours of wholesome fun. The jelly produces different sounds based on its shape, salt concentration and finger contact. The thinner the jelly the greater the conductance.  Conceptually it's similar to the Theremin, except this is variable capacitance instead of induction.

What this reminds me of are RF testing modules. In RF testing, instead of using actual humans (who are highly variable and uncooperative) they use a plastic bag filled with a concentrated solution of salt and water as a substitute. It's conductivity is very similar hence the stand-in.
