[Leight] posted an interesting use of the LCD Shield by SparkFun as a waterfall visualisation (a.k.a. plotting signal strength and frequency over time). “Cascata” is the Italian for “Waterfall”. Nice one.

Cascata is an Arduino Waterfall display program built using the Arduino and the Sparkfun Color LCD Shield. It has a selectable 0-4 kHz or 0-2 kHz audio range, and can display a waterfall, a spectrum graph, or both. It features variable attenuation and automatic DC centering.
