The reality is I kinda like the rock. I don't see the need for a piece of hardware or a program when the rock works fine. There is something to be said for simplicity and I don't think its gonna get any simpler than a rock. It's basically an on/off switch.

I have a children's science textbook from the 1930s that describes all sorts of experiments with electricity kids can do with the power outlets in their home. What could go wrong?
