Thought you might be interested — my friend Harvest and I implemented this adaptation of Disney’s Touche touch sensing system for Arduino, and used it to turn a mug of water in to a musical instrument. The extra parts cost about $1-2; everything else (Arduino, breadboard, mug) you probably already have lying around.
And it was so much fun! We got pretty sensitive and robust gesture sensing working — we could tell how many fingers they had on the outside of the mug, when they touched the water’s surface, etc. So then we used ChucK (a musical programming language) to turn it into an instrument.
Full blog post, including github w/ all relevant code and sound files, as well as links to an Instructables here!
Theoretically this should work with any conductive surface (e.g. people, plants, large metal objects, etc) but we haven’t tested it on other things yet. Would love to hear from anyone else who wants to try this. We owe a lot to other people who have posted similar things; it’s adapted from Disney’s Touché technology (full credits in the Instructables post/github)…

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
