Check out Amplitude, $0.99 I think. Allows you to greatly increase the gain on the iPhone's microphone to use for eavesdropping purposes (need headphones). More interesting, it displays the waveform of the heard audio on a oscilloscope screen. So if you can whistle, you can have fun creating pretty sine waveforms.
