This project is an exploration in exploration. The user is encouraged to take a closer look at the piece, and discover an unexpected surprise. Using the brass as a capacitive touch sensor allows the user to switch on a motor that animates a hidden neopixel and a bunch of confetti.
Here is a link to the instructables that I created on how to make your own capacitive touch object! http://www.instructables.com/id/Capacitive-touch-me/
All of the components including the arduino board and the motor are housed inside of the box to conceal the mechanisms. The power cord alludes to the fact that indeed something is going to happen.
