The other day, I was doing the old 'disco-plasma-ball can use its electric fields to light a fluorescent bulb up' demo (probably my favorite demo of the year) when WH asked if he could snap a picture. Later, I saw that he was using it as his screensaver on his phone.
You can't see it, but I am, of course, muttering an evil inflected 'Muh Ah Ah Ahh" (as requested).
The old day job can still be fun!
