Great to have you aboard. It was a great first post. I knew about this stuff, but it was nice to be reminded.
I seem to recall a Mythbusters episode whit making fire from an ice lens. It worked.
And here is Fire from Coke Can and candy bar.

I live in an ice-free zone.
That being said, a cousin to the fire from ice, I attempted to start a fire from parts from a broken projection-screen TV. The lens from the projector started a grass fire from a partly cloudy sky almost instantaneously.
+1 to lens fires.
Guess it is pretty easy to forget about all of the equipment out there with lenses in it, these days.
