I completed another small project.
About a year ago I came across a small curio in a department store (Target) which was a good approximation of a neutral bit. I painted it blue, added a small pushbutton that would activate some electronics that say 'Yes!' when pressed, and added a battery compartment & speaker grill. Thus, a neutral bit with a positive charge.

Again, it's not perfect but I thought it was interesting enough to share.
