When I was a kid it was always fun to find a nice, lush piece of grass to lie down on and look up at the sky. It was doubly fun to try to spot shapes within any white, puffy clouds that were within view.
With Google's new mapping service it's now possible to do the exact opposite: Hover in the sky and look down upon the earth, looking for all kinds of shapes. This is fast becoming a popular game for some. Here's an infamous one of a swastika in San Diego. And here's one I found, of a seahorse swimming backwards in my own home town of Vancouver.
I'd love to hear about any interesting ones that you locate!
