Has anyone tried this:

It’s called “HungryFrog” and apparently it’s a game for school-aged kids that is designed to teach either latin or Homeric greek (scroll down for the greek). It’s a free download, but it won’t run on my computer because my windows is too old. It claims to teach vocabulary, grammar and pronunciation (“You hear an expert pronouce Homeric Greek aloud to help you learn Greek pronunciation yourself and help you learn Homeric Greek to speak it properly as you read the classics.”)
If nothing else, some of you will at least want to download it so you can argue about whether their expert’s pronunciation is any good.
