Great way to visualize sound

Its fun watch the display while it analyzes music, speech or other sounds. You can demonstrate how the harmonics of two tones align to make a pleasing chord. I wish the pause button was easier to hit and that the capture image menu didnt pop up so easily. But overall a good set of options for colors and sampling parameters.
