If you need a really portable version of some common jug band instruments (or just want a new way to show them to your friends) you can check out the jug band app I just created. It includes a realistic washboard, spoons, kazoo and jug. Here's a demo video to show how it works:

This runs on the iPhone, iPod touch and upcoming iPad. It includes instructions for playing each instrument, so hopefully some non-jug-band-players will run across it in the App Store and get hooked!

WoW!!!! Nice job! I am going to add that to the front page!
