Rhyme Find

I just love my "Stumble Upon" browser plug-in. It's entirely too much fun. Here's where it pointed me today:
Writer Rhymes.com
It's such a simple, elegant page, and it works -- even on my Mac! Type a word, option-click it and it gives a list of words that rhyme, divided up into 1, 2, and 3-syllable groups. Yes, I know there's a rhyming guide in the back of my dictionary, but it's not COOL like this.
