From InstallAware Software:
Rubber Ducky is a cute little aquarium display that sits neatly above your system tray. The elements of the aquarium monitor the state of your computer--fish for network traffic, plants for hard disk, bubbles for CPU usage, and water level/color for RAM usage. Whenever your system experiences a slow-down, just take a quick glance at Rubber Ducky and you will know what is holding it up at a single glance.
