Swing dancing innovations

This past weekend, I spotted something new on the sidelines of the dance floor. Chip, one of our dancers, who is a professional engineer has built himself a battery powered fan that is driven by ten "C" batteries. C-size batteries are the ones about twice the size of a fig newton or your thumb. Chip has mounted the batteries and the fan on a board which uses to cool himself between dances. The fan face is on a mount which means he can just the angle at which the gusts of air hit his body. I thought it was a cool concept but a little too geeky for me.
