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.
