Beautiful project, Rich! Would you write it up for the Nature Sounds 
Society newsletter?

A circular or square array of mikes (like "sweet 16") will begin to 
exhibit high-frequency beaming, the crossover frequency to the 
directional effect depending on the dimensions of the array. A 
vertical line array (like Rich's) restricts beaming to the vertical 
direction and stays wide in the horizontal.
