Last summer, I bought a weather frog- solar- and he glows blue in the dark. http://365project.org/pamelaf/365/2011-07-10
The joke then was that if he was wet, it was raining, if he was dry, it was sunny, and if he was gone, it was windy!
A few months later, this happened http://365project.org/pamelaf/extensions/2011-10-11
He spent the winter under the sheltering eaves but has recently emerged to resume his forecasts. In fact, yesterday, he did another face plant onto the deck!
This is his cousin, Waiter Frog. He shines greenly in the dark and is still waiting :-) for his first assignment. Carry on, Mr. Frog!
