Quite a few years ago my daughter made a life casting of her foot for a science fair project. I was curious how this would work for a hand holding an object. I did this one of my hand just for fun with a light bulb in it.
I later added an Adafruit Trinket with a NeoPixel and a simple program to make it flash as you see in the video below. I was trying to achieve the effect of an old fashioned fluorescent light and ballast striking on startup. I think it worked out pretty well.
This hangs in the roasting lab and runs whenever I am roasting coffee now…
