"And they could double as umbrellas"

Now, there's a market opportunity for some enterprising, physics-unchallenged inventor...
Umbrellas which glow (for second or so) at the point where the raindrops hit...

I'll (almost) bet it's possible. It might make a new sensation if anyone took it up..:-))

Probably not in my price-range though...

Ahem....

MRIguy: I quite like your image, but find it a little bland. Nice technique, well done! - but a little more variation required. It seems too obviously cloned, all the shapes the same (and even mushrooms do have personality, as your "real world" pic shows..)

Just my personal opinion, of course.
