"Bounce" Tap Metronome
This is just a dopey little program I wrote so that I could determine the tempos for rock tunes, which I use to pace myself while jogging. (Lately I'm feeling pretty slow, running 150-154 bpm. 124-134 bpm was also useful for when I was into "power walking.")
So you tap out a tempo on the keyboard and the metronome measures it in BPM (beats per minute). The little happy face keeps bouncing along to the tempo you've selected so that you can be sure of an accurate reading.
It should run on any basic Windows system.
