From the guys who brought you the C5 NXT Blimp, have a look at this awesome industrial color and size sorting plant commissioned by Dynaway. This model is used to demonstrate their manufacturing execution system.
It sorts 2x4 and 1x2 bricks in size and color. The bricks get sorted directly into pallets in a high bay storage system. When a new color is detected, an empty pallet in the high bay storage is assigned to the color. When a pallet is full, a robot retrieves it, and returns a new empty pallet.

There are 7 NXT’s in the plant, and they all communicate with each other and a PC application over Bluetooth. The software written in leJOS, with is a java language for MINDSTORMS®.
