Description

Haven't you always wanted to play Guitar Hero... But with Jugs??  Enter Jug Hero.  This little program allows the user to blow on various jugs, following along with a computer-generated screen which gives the user direction for which jugs to blow.

As a bonus, the user can determine the speed of the computer program depending on how fast or slow they want to blow.
