Silly, but cool idea

I read somewhere that a fitting headstone for Bob’s grave would be one that looks like a Moog modular P cabinet.

My wife instead suggested something novel: it should look like a theremin and make a whooooo noise when you approach the grave.

Hope this doesn’t seem disrespectful.
I knew Bob and am certain he’d be laughing heartedily at the idea.

This is a great thought. I reckon Bob would probably laugh too - I certainly did!
