I Want Your Lily Frond!

Reading through a few of my favourite blogs, one of them gave a link to this mathematical puzzle which takes on a fun front. The key is to get the brown frogs over to the lilies where the green frogs are sitting on, and vice versa. Sound simple enough? Its mentally stimulating enough to keep you engaged, while easy enough for you to solve in 5-10 min. Throw on realistic frog croaks and rushing waters, and you've got a winning game. Got 15 min to kill? What better way to spend than switching frogs on lilies...
